If you are building an AR-15 or changing out some parts on one you already have, I’m sure you’ve run into this dilemma before. Is a carbine or mid length gas system better for my AR?
In this article, we will go over some of the key facts of the gas system, and make some very simple recommendations about which gas system is better for you.
The gas system of an AR-15 is what allows the weapon to cycle. Once you fire the weapon, gas is generated by the chemical reactions of the propellant of the cartridge. This gas pushes the projectile forward, but also work to cycle the bolt.
Related: If you are using ar15, i highly recommend the best ar 15 scope for the money, it is useful.
It is actually pretty simple how this is accomplished. The gas system has a small hole to vent gasses that is near the front sight post of the weapon. The vent hole is connected to a gas tube, that goes back into the receiver.
Once the bullet passes the vent hole, the gas will enter this hole and flow through the gas tube until the bullet exits the barrel. Once the gas moves back into the receiver, it provides the power for the bolt carrier group to chamber the next round.
However, after the bullet exits the barrel, the gas won’t all vent through the small vent hole anymore. Most of it will vent through the end of the barrel.
As you can imagine, this all happens pretty fast.
Carbine length gas systems are shorter than mid length gas systems. What this means is that the vent hole is closer to the receiver on a carbine length gas system. In turn, that means that the vent hole is further from the end of the barrel.
The length of the gas system affects the cycling of the weapon. If the bullet is past the vent hole but in the barrel for a longer amount of time, more gas will enter the vent hole. So, if the vent hole is closer to the barrel, less gas will enter the gas tube.
In a carbine length gas system, there is a greater distance between the end of the barrel and the vent hole. This means that more gas will enter the gas tube when compared to a mid length gas system.
On a standard 16 inch or an 18 inch barrel, we recommend a mid length gas system.
The reason for this is that a carbine length gas system will allow more gas to enter the tube, which will increase recoil, and will cause additional wear on the internals of your weapon.
On a 14.5 inch or shorter barrel, we recommend a carbine length gas system. With this shorter barrel, there is less space between the vent hole and the end of the barrel, so the correct amount of gas will enter the gas tube.
If you are using a 20 inch barrel, a rifle length gas system should be used.
The AR-15 is an extremely popular weapon, for a variety of reasons. Due to the number of internal parts and external accessories available, it is a very common weapon for people to build.
Many people like to build their own AR-15s because it allows them to fine-tune exactly what the weapon can do for them. It also gives you a better appreciate for the weapon as a whole, while allowing you to customize nearly every aspect of it.
No matter what the part is, there’s bound to be hundreds of different manufacturers making one. With this wide assortment for each individual part, it’s easy to see how customizable the AR-15 platform can be.
But, before looking into building your own AR-15, one very important decision must be made. What caliber do you want the weapon to shoot?
Now, this is a simple question with a plethora of answers. For brevity’s sake, I will keep this list to some of the most common builds. I will also focus on calibers that can be built on the traditional AR-15 lower.
The biggest limiting factor in the caliber is the size of the magazines and magazine well. As you will see, there are some extremely large caliber bullets that have been fit into short casings. These rounds were designed specifically for AR-15s.
However, some of the classic larger caliber cartridges, such as .308 Winchester and .338 Lapua, are longer cartridges that won’t fit into the magazine well of a standard AR-15 lower.
If you do a little research, there are a few common calibers that you can build an AR-15 in. Some of these are: .223/5.56x45mm, .300 Blackout, 6.5 Grendel, .458 SOCOM, .50 Beowulf, 6.8 Remington, and .22LR. While there are countless more options, these are just some of the most common. We will briefly go over each one, and make a few recommendations.
This is the classic. A “normal” AR-15 fires .223. It is a fun to shoot round that is easy to find. There are many different ammunition options available to you.
We recommend this caliber for general shooting, varmint hunting, and potentially competitive shooting. With the proper gun, this could be decent at longer ranges.
Due to the cheap prices available, it is also a good round for plinking.
This is one of the most popular options out there. It is a .308 bullet in a necked down case. As you can imagine, this provides excellent terminal performance, but will die off at distances greater than 300 yards.
We recommend this one for home defense and medium game hunting. This would definitely be suitable for deer hunting.
6.5 Grendel is somewhat of a jack of all trades. It was designed to be an improvement over the traditional 5.56x45mm cartridge, in terms of ballistics and effective range.
The bullets are larger and heavier than 5.56x45mm NATO, but they are fired slightly slower. Due to the added size and weight, these rounds will perform better in a target. 6.5 Grendel also offers a greater effective range than 5.56x45mm NATO, and can be shot out to around 1000 yards.
We recommend this caliber for long range shooting, competition shooting, and potentially some hunting. While there are better options for deer hunting, this caliber would be acceptable in the eyes of most.
These two calibers are lumped together because they are so similar. They are both extremely large bullets that are in a specialized cartridge that will fit a standard AR-15 lower.
The .458 SOCOM came first, after demands from the special ops community for a round that had more stopping power than the traditional 5.56x45mm. The projectiles of both of these cartridges are absolutely massive.
For home defense, these rounds can’t be beat. However, keep in mind that the range of these calibers is severely limited due to the weight of the bullets. Similarly, they are popular rounds for big game hunting at close range. Simply put, whatever you hit with one of these rounds will go down.
6.8 Remington is similar to 6.5 Grendel in that it was designed to be an improvement over 5.56x45mm NATO. The projectiles are larger, but are fired slightly slower than the 6.5 Grendel projectiles.
The projectile is actually from a .270 Winchester cartridge. Most hunters know that this round is extremely popular in the deer hunting community. For this reason, this round is another option for deer hunting. We prefer .300 Blackout, but 6.8 Remington will also work. The range of this round is slightly greater than that of .300 Blackout.
As backwards as it seems, you can build an AR-15 in an AK-47 caliber. However, there are a few reasons that we recommend not doing this.
First, 7.62x39mm is generally considered inaccurate. Part of this comes with being shot from an AK-47, but it also comes from the round being less accurate than some of its competition.
Second, due to low gas pressure, a traditional AR-15 may have trouble chambering a 7.62x39mm round repeatedly. We would avoid that.
The size of the bullet is great for terminal performance, but it is also very similar to .300 Blackout. While 7.62x39mm is a viable option, .300 Blackout can outperform it in almost every aspect.
The one plus side that 7.62x39mm does have is that the ammunition is cheap.
Many people know that .223, or the classic AR-15, is actually very similar in size to a .22LR projectile. There are plenty of conversion kits out there that will allow you to shoot .22LR from an otherwise stock AR-15.
Due to how cheap this rimfire ammunition is, this is a great round for plinking and for teaching firearms safety. best ar 15 scope for .22lr is good option for ar15 owner.
Similarly, there are conversion kits out there to allow your AR-15 to shoot pistol cartridges. These are nifty, but in our opinion, they lack much of a purpose. For general rifle shooting, there are far better options out there.
As you can see, there are quite a few options out there. Keep in mind that this is just the beginning, and there are even more calibers available to you!
While it can seem like a difficult decision to make, keeping in mind what the weapon is for will help to make the decision.
Finding out your shotgun effective range can be important for a variety of reasons. No matter if the shotgun is being used for hunting or defense, it helps to know how far you can be from the target to have the result of putting the target down.
This is especially important when it comes to protection but you don't want that deer walking away either.
Their are a few factors that go into a shotguns effective range, and if you continue reading, you will find out what those are so you can figure out the effective range for your gun.
Their are three main things that effect the effective range of your shotgun.
Two of the three can be changed by you, so you can increase your effective range if needed, or create a set up that has a farther effective range. The mental state of the target can not be changed by you however.
You may be wondering how the mental state of the target effects the effectiveness.
You were probably thinking only the gun and ammo mattered, but that isn't the case.
If the target is angry or has an adrenaline high, then you will have to do more damage to it to bring it down.
This means having more of your ammo hit it. The situation is even worse if it is a home invader who may be on drugs.
Well, that is where the type of shotgun and ammo comes into effect.
Bird shoot for example shoots out a lot of small pellets and because they are small means they spread more.
Buck shoot on the other hand doesn't spread as much and has larger rounds so you need fewer to hit the target.
Lastly a slug spreads even less, but because of this you need better aim to hit the right spot.
Having a chock on your shotgun can effect the spread though, and that is why it is not just the ammo that effects the effective range of a shotgun. A chock forces the load into a smaller compact area before leaving the gun. This means that the ammo doesn't have room to spread as far.
If you are a better aim or have a good sight, then you might be able to squeeze in a few more feet for your effective range.
Practicing with your gun and knowing how it handles is a good way to increase your skill.
A good rule of thumb though is most shots spread about one inch per foot back, so if you need a grouping that is thirty inches to hit the vital area of a person, then you should be at most thirty feet back.
This is just a basic rule though, and practicing with your gun can help you figure out how much spread your grouping has.
Finding the best set up to increase range is hard.
Skill is a big part of it and practicing is the only way to importer that. Some other things you can do though is choose an ammo that doesn't spread as much.
Most peoples go to is 00 Buck Shot. This has a good spread pattern and has large enough rounds to do lethal damage. Their are some advantages to bird shoot though for home defense.
At close range it has enough little pellets to do a lot of damage. However, these little pallets have a hard time making it through doors and walls, so others will not get hurt.
You need to consider the compactness of it and also consider the type of chock it has.
If you are going to be hunting birds, then you want spread, but for larger things you might want the barrel to be reduced by a chock.
The best thing is to consider the primary purpose of the shotgun when you go to buy it. For home defense you will want a different gun than for bird hunting.
Their are a lot of reliable options on the market, and you can find one that meets your needs and gives you satisfactory results at the range you want.
Get for you best scope for shotgun also help you have best result when shooting
Now you know that there are a few factors that goes into a shotguns range and they don't just start and end with the gun and ammo.
While the ammunition of choice and the chock and sights of the gun play an effect. The mental state of the target and your skill are also factors.
Effective range of a shotgun can vary from person to person and target to target. The key thing is that you have enough ammo hitting the target at vital points.
The spread of the ammo combined with your distance determines this and with practice you can learn the effective range of your shotgun.
In the modern age, almost all shopping is done online. Even grocery shopping can be done completely online now. So, with these technological innovations and changes, how does the firearms community change with it?
Wondering if you are able to buy ammunition online? Let’s take a look at some of the laws to keep in mind.
The short answer is yes, you can buy ammunition online. However, as with almost anything in the firearms industry, there are some stipulations.
In some areas, ammunition can’t be shipped in. A few examples are New York City and Washington D.C.
In other areas, you can’t get it shipped to your house. Similar to purchasing a firearm, ammunition can only be shipped to a federal firearms license holder in these areas. Some of these are Massachusetts, New York, Chicago, and most of California.
Lastly, in Illinois and Connecticut, you have to have paperwork on file in order to be eligible to buy ammunition online. Some of this paperwork could be permits or IDs.
The biggest takeaway is to make sure you know the laws in your area. Generally speaking, you can find them with a quick Internet search. However, there are also some websites that have compiled multiple states’ laws into one location. One example is this page on Able’s Shooting: https://www.ableammo.com/catalog/how-to-guns.php
However, keep in mind that laws can change. Always double check your own state laws before relying solely on that website or others like it.
There are a few other considerations that apply when buying ammunition online. For example, most websites have to charge extra for shipping due to the fact that they are shipping a hazardous material. Federal hazard classification is required, so it costs more money.
It is also common that weapons and ammunition must be purchased separately online.
Many different websites will not ship to Alaska and Hawaii, so be sure to keep that in mind if you are in those areas.
There are a couple differences between buying ammo online and buying it at the store. The primary ones will be the price and the fact that you can’t actually see the ammunition
While it is not set in stone, there is a good chance you can get a better price online. However, keep in mind that you will have to pay for shipping. Also, some stores will do price matching, so you may be able to get the price in the store down.
For some people, not being able to physically see the ammunition may be a little difficult. Especially if you are newer to firearms, physically seeing the ammunition may make you a little more comfortable that you are getting exactly what you need.
When buying online, there won’t be a store representative there to answer your questions. However, many websites will have frequently asked question pages or online representatives to assist you.
When you buy ammo online, you will not be able to return it. Similarly, nearly every store will not accept returns on ammunition for safety reasons, so there’s not much difference there.
There are hundreds of different places online that you can buy ammunition. Brownells, Lucky Gunner, and Cheaper Than Dirt are always popular options, but there are more than a few.
Brownells has the largest supply of many different types of weapons and ammunition, but they can sometimes be beat in price by Cheaper Than Dirt. With these two websites, you really can’t go wrong.
For reloading, I have found that Brownells has a wider variety of products. MidwayUSA also has a great selection of reloading supplies.Cabela’s and Bass Pro Shops also sell ammunition, but they usually sell at the exact same price as in the store, so there wouldn’t be much incentive to buying online, unless you live in an area where you can’t easily get to an outdoors store.
Just getting into weapons? Looking for your first rifle? Trust us, we understand the feeling! Everyone has to start somewhere.
This guide will provide a few key factors to keep in mind, which will hopefully help in your decision making.
Let’s get started!
Before getting into anything, we are going to assume that you have a general understanding of firearms safety, and are familiar with the process of purchasing a firearm.
There are a few basic terminologies to understand before getting any further.
Action. Action refers to the way in which the rifle ejects the empty shell after firing, chambers the next round, and fires that next round. A few examples are: semiautomatic, fully automatic, bolt action, lever action, and pump action.
Magazine. The magazine is a device that holds ammo. It is usually spring loaded to assist in feeding the next round into the chamber. The magazine capacity is how many rounds the magazine can hold.
Caliber. Caliber refers to the size of the bullet that the weapon fires.
This has to be the first question that crosses your mind when you start shopping for a rifle. What are you going to use it for?
Generally speaking, a hunting rifle is going to be much different than a plinking rifle. Identifying your use for the rifle will help to pick which factors are important to you.
Durability and reliability are extremely important. As you are hunting, there is a chance it will be exposed to the elements.
Identifying what you are going to be hunting for will help to pick the caliber. Do your research, there is plenty of information out there on the best caliber for different animals.
When looking for ammunition, there is a plethora of hunting-specific ammunition. There are some great options, and you really can’t go wrong with Federal Power-Shok, Remington Core-Lokt, or Winchester Deer Season, although these are just a few recommendations.
Generally speaking, jacketed hollow point ammunition will expand on impact and cause a lot of damage, which helps to bring down the target. However, when using a larger bullet, such as .308, this becomes less important.
As far as action is concerned, hunting rifles are commonly bolt action and lever action, as they are more reliable. However, semiautomatic rifles are becoming more and more popular.
For some types of hunting, such as hog and coyote hunting, semiautomatic may even be preferred. Pick the best ar15 scope for deer hunting will be good for you.
These competition grade weapons are usually pretty expensive, and are commonly bolt action as well, as they are slightly more accurate than their counterparts. However, more and more precision rifles are semiautomatic.
As far as caliber is concerned, it really depends on your range.
If you are planning to do some accuracy shooting at longer distances, 6.5 Creedmoor, .300 Win Mag, and .338 Lapua are all excellent choices. For closer ranges (think 400 yards and closer), 5.56x45mm NATO (used in AR-15s) is popular because of the number of aftermarket parts and accessories available.
When it comes to ammunition choices, there are plenty of options available specifically for accurate shooting. Lapua ammunition is notoriously accurate, as are Hornady Superformance and Federal MatchKing.
When you pull that trigger, you need to be sure that you are going to be firing at the threat, whatever that may be.
Semiautomatic is generally preferential, as you would be able to shoot faster at a potential threat.
As far as calibers are concerned, 5.56x45mm NATO is a popular choice (AR-15), but some prefer larger calibers, such as .308 Winchester.
The caliber is slightly less important than the ammunition chosen. High quality defense ammo, such as jacketed hollow point ammunition, is very important, as it will do the most damage on impact.
As wrong as it sounds, if the ammunition is good for bringing down large game, it will also be good for bringing down a potential intruder. You should keep rifle in best gun safe for the money to make it work stability.
They don’t need to be too fancy or durable, as it is a just for fun gun. While not always true, the caliber is usually not that big of a deal for a rifle that is only for fun.
However, some people very strongly about having fancy, semiautomatic, large caliber weapons for plinking. My personal view is that I just need something basic, as I’m only practicing my skills for when I bring out my “real” guns – my competition shooting weapons and hunting rifles.
I practice with a bolt action .22LR that cost less than $300.
If you are looking for a home defense weapon, I really don’t think you can go wrong with an AR-15 or AR-10. With the number of aftermarket parts and accessories, you will be able to accomplish almost any type of shooting with this weapon.
For plinking, I recommend something simple, like I mentioned before. However, if you are just getting into weapons, I would recommend an AR-15. This is an easy recommendation to make, due to how ridiculously popular the weapon has become. They perform well and will let you meet many needs.
For precision shooting, I would look into anything made by Weatherby, Tikka precision rifles, and Howa precision rifles.
For hunting, it really just depends. However, the Ruger American is a basic bolt action weapon that is durable, reliable, inexpensive, and is available in just about every caliber imaginable. There are better options, but for the price, this is a great weapon.
There are hundreds of different factors to consider when buying your first rifle. This guide has hopefully given you a general concept of what to consider.
To the beginner, rifle reticles can be a bit overwhelming.
There is a lot of terminology used that can be quite confusing, and the different types of reticles and scopes can be confusing as well.
Wondering how to make sense of rifle scope reticles? In this article, we will go over some of the basics to give you an understanding about scopes in general.
For starters, a reticle is the aiming point of a scope. In simpler terms, it’s the “crosshairs” if you will. It is the internal part of the scope that you use to aim where you want to shoot.
The crosshair reticle is exactly what it sounds like. It has thin lines that meet in the center. That center is what you use as your aiming point.
However, there are crosshair style reticles that have thicker lines. Some of these are called duplex reticles and German numbered reticles.
A BDC reticle is generally a modified crosshair or duplex style reticle. BDC stands for bullet drop compensating.
Basically, it is a reticle that has some type of markings below the center of the crosshairs that you can use to anticipate bullet drop over an extended range.
A BDC reticle is generally a crosshair or duplex style reticle that has some dots or markings below the center.
If you are finding BDC reticle scope for ar10, check this post about best ar10 scope, it will helpful
Another modified crosshair or duplex style reticle is the mildot reticle.
A mildot reticle is a reticle that uses tiny milradian dots on both axes of the crosshairs as a measurement.
A mildot reticle allows you to find the approximate distance your target is at. The math behind it can be pretty confusing, but that’s what it boils down to.
A dot reticle is something you might find in a tactical style “red dot sight.” It uses one dot in the scope as the aiming point.
Generally speaking, they are illuminated.
Illuminated reticle refers to a reticle that has some type of light.
Whether it’s a battery-operated dot or a fiber optic scope, it is some type of illumination that will allow you to see better at night.
However, certain colors also help to see during the day.
Keep in mind that many of these reticles can overlap one another. For example, there could be an illuminated duplex BDC reticle, which would combine a few of these basic categories.
That may have been a lot to take in. I’m sure you’re wondering in which shooting situations each reticle type would be best.
For any kind of precision shooting, you really want a thin crosshair style reticle.
The thin crosshair is paramount because the smaller the reticle is, the less amount of target surface area that is covered by the reticle.
When you are attempting any type of shooting that requires extreme accuracy, you want to be able to see as much of the target as possible.
What type of Reticle For hunting:
Duplex style reticles are very popular.
The reason behind this is that the wider legs of the crosshair allow the hunter to easily acquire a target and get his reticle centered on target faster.
For Long Range Hunting
BDC reticles are popular for long range hunting. However, dependent on the type of hunting, a thin crosshair may also be good for long range hunting. For any type of long range shooting, BDC reticles are a decent option.
For Snipner Shooting or Tatical Use
For any kind of sniper shooting or tactical use, mildot reticles are popular. However, for the common person, the math and adjustments that go into a mildot reticle can be a little confusing, and are probably a little overkill.
Obviously any kind of shooting or hunting at night would make an illuminated reticle very important. However, it is worth mentioning that a low quality illuminated reticle will be way too bright, making it difficult to acquire your target.
As you can see, there are quite a few different kinds of reticles, each of which comes with their own pros and cons.
There are quite a few factors to consider, but hopefully this basic overview has cleared up some of the confusion with the different types of reticles.
Essentially, when you need extremely accurate shots, a thin crosshair is in your best interest.
For hunting, a wider duplex reticle will make it easier and faster to acquire your targets.
At long distances, a BDC or mildot reticle can help to adjust your shots.
When shooting at night, an illuminated reticle would be extremely helpful.
Other than that, there are many different combinations of reticles available, so you should be able to fill more than one need with a single scope. Dot sights are becoming more and more popular, for all different kinds of shooting.
Keeping these basics in mind will help to clear up some of the confusion.
With the number of shotguns available, it can be difficult to decide which one is right for you.
In this article, we will go over the key factors to keep in mind when choosing a shotgun, and we will make some recommendations for which shotguns will meet which needs best.
When someone talks about the gauge of a shotgun, they are talking about the diameter of the barrel. In turn, this also means that they are talking about the size of the shell that the shotgun can shoot. 12 gauge and 20 gauge are the most popular, but there are actually quite a few different gauges available.
Here’s a list of the most common shotgun gauges, from smallest to largest:
There are other shotgun shells that exist, but are extremely uncommon. Often, these shotguns will require custom ammunition.
When it comes to shotgun actions, it essentially boils down to pump action, semiautomatic, and double-barreled shotguns.
Pum action shotgun: Pump action shotguns are the most common. They are inexpensive, reliable, and easy to use. A pump shotgun will excel in almost any use.
Semiautomatic shotgun: It don’t have a pump. They function using gas blowback, meaning that all you have to do is pull the trigger. They allow for much faster shooting, but are more expensive, and their reliability is questionable.
Double-barreled shotgun: whether over under or side by side, are breech loaded weapons. They are extremely reliable, but can also get expensive. Due to the fact that you only get two shots, these are popular weapons for shooting skeet.
Longer barrels will be better for shooting skeet, while shorter barrels are very popular for home defense and tactical applications.
Generally speaking, hunting shotguns have a barrel in the neighborhood of 26 to 28 inches long.
Some folks will buy a shotgun for deer hunting, as they are unable to shoot rifles in their area.
If you’re buying a shotgun with the sole purpose of shooting slugs, it would be in your best interest to buy a shotgun with a rifled barrel.
Due to the size, weight, and recoil of a shotgun, it becomes very important to have a shotgun that fits you well.
Make sure that the stock is comfortable, and you are able to easily sweep the barrel.
Which Shotgun Is Right For you
For home defense, we recommend a pump action 12 gauge with a shorter barrel.
For waterfowl hunting, a 12 gauge is an excellent option. Both pump action and semiautomatic will perform well, but semiautomatic will allow for faster shots, which may be helpful.
For upland bird hunting, we recommend a 28 gauge. It is extremely lightweight and fast to shoot. However, many other gauges will work well for this use. 20 gauge is another great choice. As far as action, any will work.
For deer hunting, we recommend a pump action 20 gauge or 12 gauge with a rifled barrel will perform well. This is good shotgun for deer hunting, you should choose the best shotgun scope to have best target.
For skeet and trap shooting, 12 gauge is extremely popular. A 12 gauge double-barreled shotgun with a longer barrel will perform exceptionally well.
For general shooting, a pump action 20 gauge is a great choice. It is lighter and kicks less than 12 gauge, making it more enjoyable to shoot.
Hopefully this article has taken some of the guesswork out of buying a shotgun for you.
There are a few factors to consider, but having this knowledge and comparing it to your desired use will make it easy to select a shotgun.
Wondering how far a bullet can travel?
The projectile of a rifle cartridge, often called a bullet, can travel at vastly different distances, dependent on a few key factors, that can be dumbed down to basic physics.
The main factors that will affect how far the bullet can travel are: projectile weight, muzzle velocity, trajectory, shape of the bullet, and environmental factors.
Here’s some physics that will blow your mind: if you were to fire a rifle and drop a bullet at the exact same height at the exact same time, the two projectiles would hit the ground at the exact same time.
However, how far downrange would the fired bullet be?
If two projectiles are fired in the exact same way, at the exact same velocity, the heavier one will travel slightly further.
The reason for this is that the heavier projectile will have less drop, which means it will travel further before its velocity slows down enough for the resistance of the air to actually significantly slow the bullet down.
Once the air resistance begins to slow down the projectile significantly, the projectile will begin to tumble through the air, which causes it to slow down and eventually fall.
If two projectiles of the exact same weight are fired the exact same way, the one that is faster will travel further.
The reason for this is the same as the previous one. If the bullet has a greater speed, it will take longer for the air resistance to slow the bullet down.
The primary things that will affect the muzzle velocity are the specific cartridge used and the barrel length.
A cartridge with more powder will produce more muzzle velocity, and longer barrels produce more velocity as well.
This one boils down to aerodynamics. A longer, skinnier bullet will travel further because it is more aerodynamic. It cuts through the air easier, which allows it to travel further.
Increased resistance on the bullet slows it down faster, which then decreases the distance it can travel.
At higher altitudes, air is thinner, so the bullet will travel further.
At lower altitudes, the air is more dense, so the bullet will experience more resistance, and won’t be able to travel as far.
Similarly, cold air is denser, so a bullet will travel further in warm air.
Wind can also affect how far a bullet can travel, as it will blow the bullet side to side as it flies through the air. To preserve ammunition, you should have the best gun safe with dehumidifier, it will help you ammo have good quality.
As you can see, there is no easy, one-size-fits-all answer to this question.
It is entirely based on the other factors.
Thinking about these factors, you will be able to easily decipher what has the most impact on how far a bullet travels, but there is not one number answer to give.
With enough research, you could find a general idea for multiple calibers of weapons, but even then, these factors all apply.
Even if both rounds are 5.56, different rounds fired from different weapons in different environments will significantly change how far the bullet is able to travel.
The M4 Carbine used in the military and the civilian AR-15 are extremely similar weapons.
Wondering what the differences are?
Look no further. In this article, we will go over some of the similarities and differences between the two weapons.
To start, we will talk about the history of both weapons.
The AR-15 was originally created by Armalite in the 1950s, but due to financial issues, they sold the rights for the weapon to Colt.
Colt began producing the Colt ArmaLite AR-15. It was designed to be a lightweight assault weapon, so as a result, Colt pitched the weapon to multiple militaries.
After some modifications by Colt, the rifle was introduced in the military as the M16.
The M4 was created as an improvement to the M16.
Once the military realized the need of a weapon that could operate in close quarters, a shorter and lighter version of the M16 was created.
The M4 was designed in the late 80s to early 90s, before being accepted by the military in the mid 90s.
Compared to the M16, the M4 features a shorter barrel and a collapsible stock, as well as a few lighter parts to cut down on the weight.
if you have ar15, you can find the best ar15 scope, it will help you have good result in shooting
To compare the M4 to the AR-15, we will start with the differences because there are so many similarities.
The differences between the two are extremely small. The M4 has a 14.5 inch barrel, while the AR-15 generally has a 16 inch barrel, although multiple sizes are available.
The primary reason for this is the law in the United States about short-barreled rifles. This law requires that rifles have at least a 16 inch barrel.
As a result of this shorter barrel, the M4 has a shorter gas tube. To deal with the decreased pressure as a result of this shorter gas tube, the M4 also has more pronounced feed ramps to ensure that the next round is seated properly each time.
The barrel of an M4 has an hourglass shape cut into it, which allows for military members to mount a grenade launcher to it. The last big difference between the two is that the M4 has either a three round burst or fully automatic firing option.
As you can tell, there are very few differences between the two weapons.
The internals of the upper and lower receivers are very similar in both weapons.
The bolt and bolt carrier group of the two are the same.
The charging handle is the same.
The trigger and trigger assembly are the same.
Externally, the handguards and rail systems can be the same, dependent on which one you have on your AR-15.
Here is video about the fact you should know before buy M4 or Ar15
This is pretty much a trick question. Many people don’t know this, but the only way to get a true M4 is to go and talk to your local military recruiter.
The civilian AR-15 functions the exact same and is pretty much identical, but it is not the exact same as a true M4.
However, it is possible to get an AR-15 with the shorter barrel, as long as you have the proper tax stamp.
You can buy the exact same handguards as an M4, and could find a milspec lower receiver with the feed ramps, which would essentially give you the exact same weapon.
As far as the fully automatic feature, another tax stamp is required.
As you can see, the two weapons are extremely similar. There are very few differences between them. The primary differences are the barrel, gas tube, feed ramps, and fully automatic functioning. In terms of similarities, the two are nearly identical. If you have an AR-15, rest assured that it is extremely similar to the military M4.
When you are building an AR-15, one of the most important aspects of the build is the barrel.
Trying to decide which one is right for you? Look no further. In this article, we will go over our top five choices for AR-15 barrels. We will also talk about the different types of barrels, and what each should be used for.
Obviously, the most feature of any barrel is the accuracy.
If your rifle doesn’t shoot accurately, what point does it serve?
High quality barrels can go a long way in increasing the accuracy of the rifle.
Other features to keep in mind are the durability and the size. Certain metals will be more durable than others due to their chemical composition. A more durable barrel will last longer on your AR-15 build.
Specifically, the material the barrel is made out of can greatly increase the weapon’s accuracy.
If you don't have time, you can quickly check here:
There are two main barrel compositions:
Chromoly steel is an alloy. Barrels made from this material are the most inexpensive and are fairly accurate, but will not last as long.
Stainless steel barrels are more accurate by a comfortable margin. They will also last a little longer, because they are more resistant to corrosion. However, they are slightly more expensive and are heavier.
From there, some barrels are given either a chrome lining or nitride treatment.
Chrome lined barrels will last longer, but will decrease the accuracy.
The chrome lining will preserve the barrel and prevent corrosion even further. However, as the lining wears off, the accuracy of the barrel will be negatively affected. Nitride treated barrels will also last for a long time, but without the decrease in accuracy.
As far as the size is concerned, keep in mind the barrel length requirements in the United States (assuming that is where you are purchasing from).
If your barrel is shorter than 16 inches, your rifle will be considered a short barreled rifle, commonly referred to as an SBR. These weapons are covered under the National Firearms Act, and will require a tax stamp from the ATF. However, for our list, we will focus on 16 inch barrels.
If you are looking to do competitive shooting that requires extreme accuracy, stainless steel will be the best barrel for you.
The increased accuracy will be the most important for this type of shooting. Avoid chrome lining for competitive shooting, as the accuracy will degrade over time.
For hunting, accuracy is less important.
Especially if you will be hunting in a humid area or in the rain, resistance to corrosion is going to be crucial for this type of shooting.
The most important aspect of the barrel for this type shooting will be to ensure that the barrel is treated somehow, either with a chrome lining or a nitride treatment.
Both chromoly steel and stainless steel are resistant to the elements, so the treatment becomes the most important part for a hunting rifle. A hunter should have best ar15 bipod to hold your ar.
If you are just a casual shooter, it is dependent on how much you shoot.
If you shoot thousands of rounds per year, you probably are going to want a chrome lined barrel. It will last longer for you.
If you don’t shoot that much and clean your rifle adequately, any barrel choice will work for you. In this situation, we would recommend a stainless steel barrel due to the increased accuracy.
First on our list of best AR-15 barrels is this 16 inch cold hammer forged barrel that is made of chrome moly vanadium.
The fact that the barrel is cold hammer forged creates an excellent barrel. It has a 1:7 twist rate, weighs 1.75 pounds, and has a chrome liner on the inside of the barrel.
The pros of this barrel are the durability and reliability. These features come mostly from the chrome lining and the phosphate exterior finish. Despite the fact that this is a chromoly barrel, the chrome lining will increase the durability. The reliability is backed by Daniel Defense’s warranty to protect against any material defects.
The cons of this barrel are the price and accuracy. This is the most expensive barrel on the list. While this is the most accurate chromoly barrel, stainless steel barrels will still be more accurate.
Next up is this lightweight stainless steel barrel from Modern Armory. This barrel has a 1:7 twist rate and weighs 1.25 pounds. Since it is stainless steel, this is the best AR-15 barrel for accuracy shooting.
The pros of this barrel are the light weight, accuracy, feed ramps, and the lifetime guarantee. The fact that this barrel is so lightweight gives you the pros of a stainless steel barrel without the primary con. The accuracy of this barrel is unquestioned; Modern Armory guarantees 1 MOA accuracy at 100 yards when it is used properly. Another great feature is the feed ramp, which will help to ensure a round is smoothly chambered each time. The barrel is also available at an excellent price.
As far as cons, the gas block and gas tube aren’t included in the base price, but are still relatively inexpensive.
Next up is another 16 inch chromoly steel barrel. The barrel has a nitride finish for increased strength and durability. This barrel weighs 2 pounds and has a 1:8 twist rate.
The pros of this barrel are the durability, feed ramp, and price. Due to the nitride finish, this is an extremely durable barrel, and the accuracy will not be as negatively affected. Bear Creek Arsenal expects sub 1 MOA accuracy from this barrel. It is also available at an excellent price.
The cons of this barrel are the weight. As you can see, this is a heavier barrel, so that is something to keep in mind. Another potential con of this barrel is the overall quality. The previous chromoly barrel was cold hammer forged, which increases the quality. However, Bear Creek Arsenal barrels are individually inspected to guarantee their quality.
This 16 inch chromoly steel barrel weighs 1.5 pounds and has a 1:8 twist rate. The barrel has a parkerized finish, similar to what the military M4 barrels have. It is the most affordable on our list, and is the best AR-15 barrel for the basic build.
The pros of this barrel are the price and weight. Don’t let the price fool you, Anderson Manufacturing is well known for their quality, and this barrel is no different. However, this price is available at an extremely affordable price. The weight of this barrel is one of the lowest as well, so it would work well for a lightweight build.
The cons of this barrel are the durability. Due to the fact that there is no chrome lining or nitride treatment, this barrel will not be as durable as some of the others.
This barrel from Rock River Arms is a chromoly steel barrel with a chrome lining. The twist rate is 1:9, and the weight is over 2 pounds, although that weight does include a bayonet lug, barrel nut, handguard cap, and the front sight post. Without those parts, this barrel would be close in weight to most of the others on the list.
The pros of this weapon are the durability. Due to the fact that the bore and chamber are chrome lined, this rifle will last thousands and thousands of rounds of ammunition.
The cons of this barrel are the price and accuracy. This is among the most expensive barrels on our list. As previously talked about, accuracy is negatively affected when a barrel is chrome lined.
As you can see, there are plenty of different features and factors to consider when looking into buying a barrel for an AR-15 build.
When looking to purchase, keep in mind the accuracy you require, how much you plan to shoot, and how much you would like to spend.
Also keep in mind any local laws about minimum barrel lengths.
While it is by no means an all-encompassing list, we hope that our list of best AR-15 barrels has at least pointed you in the right direction.
