1. Bushnell Trophy TRS-25 Red Dot Sight Riflescope

Bushnell Trophy TRS-25 Red Dot Sight Riflescope

Bushnell Trophy TRS-25 Red Dot Sight Riflescope

This red dot sight from Bushnell is extremely compact. It measures only 2.4 inches long, and only weighs 3.6 ounces. You will hardly even notice that it’s attached to your rifle.

Similar to the previous optic, this scope has unlimited eye relief. You can shoot it with your head placed wherever you want, and with both eyes open. As long as your zero is accurate, your shots will be on target. Just like with the Vortex, this allows for extremely fast target acquisition.

In terms of light transmission, this scope performs almost as well as the previous Vortex. It has Bushnell’s Amber-Bright technology and the internals are fully multicoated. The front lens of the scope is amber in color, which improves your vision down the sight. However, this scope isn’t quite as bright as the previous one, due to the fact that the objective lens is 5mm smaller. This will slightly limit the amount of light that can enter the optic.

Another similarity to the Vortex is that the scope offers a high level of durability. It is waterproof, shockproof, and fogproof. Once again, this is a great feature for hunting.

However, where this scope starts to lag a little behind the Vortex is in its accuracy. The reticle of this optic, which is a simple red dot, is 3 MOA in size. This is a pretty large reticle, so at longer distances, you run the risk of your target being completely covered by the reticle. As you can imagine, this makes it difficult for precise shooting at longer ranges.

Overall, this is an excellent value purchase. It is a quality scope, and will serve your AR-15 well. While some have experienced some issues with the newer version of this scope, we did not have any issues with ours. It was bright and easy to see

2 .Vortex Optics Strikefire II Red Dot Sights

Vortex Optics Strikefire II Red Dot Sights

I’m sure you’ve heard of Vortex Optics, as they are extremely well known and respected throughout the industry. They produce many different optical products, including quality riflescopes and tactical-style red dot sights. They offer an excellent combination of quality and affordability.

The Strikefire II is an internal reflex sight that has very bright red or green reticle. It is extremely easy to use, and offers pretty accurate shooting. The entire system is designed for AR-frame weapons, so it is naturally a great choice.

The optic measures 5.6 inches long and weighs 7.2 ounces. The objective lens is 30 millimeters, and the internals are fully multicoated, which will allow for maximum light transmission. This means that the scope will be extremely bright and easy to see through.

When you’re looking down the optic, there is no parallax and it has unlimited eye relief. This allows for easy shooting with both eyes open. The reticle is a simple dot, but there are 10 brightness levels and you can choose whether it is red or green. The lowest settings are night vision compatible. For these reasons, the sight is extremely fast to acquire targets.

When you power the scope up with the rear-facing controls, it automatically reverts back to the previous brightness setting it was on. If you accidentally leave the power on, it will automatically turn off after 12 hours. This significantly increases the battery life.

The scope itself is also very durable. It is waterproof, shockproof, and fogproof. The optic is made from an aluminum alloy , and has been given a hard anodized finish to match this. This optic would be excellent for hunting or any other outdoor shooting, due to how durable it is. Another aspect of the durability of this scope is the fact that it will hold your zero for thousands of rounds.

The adjustments with this scope are very easy to make, and each click results in a ½ MOA movement. This means that your point of impact will move by half of an inch at 100 yards. For an AR-15, this is an extremely precise adjustment, which allows for very accurate shooting.

Overall, this sight is extremely easy to use, and it is packed with features. It offers some of the best bang for your buck we have seen. We found that it was very easy and enjoyable to shoot, and we were able to shoot very accurately with it.

3. Ohuhu Red Green Dot Gun Sight Scope Reflex Sight with 4 Reticles

Nikon M-308 4-16x42mm Riflescope w/ BDC 800 Reticle,Black

Ohuhu is a company that produces many different products in quite a few different areas. One of these products is their red dot style sight, which is one of the biggest sellers on Amazon. This scope is an exposed reflex sight, which means it basically just has one external “window” where the reticle is projected. It is available in a tan color and in black.

Due to the style of sight it is, this scope is extremely small, and the adjustments are extremely easy to get to. They are made with an Allen key. The adjustments of this scope aren’t nearly as precise as the previous ones, so it will not shoot nearly as accurately.

The scope itself is decent. It has no eye relief and no parallax, just like the previous sights on our list. When it holds its zero, it is an extremely easy scope to use. However, we did have some accuracy concerns with the sight. Some of the reticles don’t line up with others, and it is known to lose a zero with a little recoil.

As the name may imply, it has four different reticles you are able to choose from, and you can choose whether they are red or green. There are multiple brightness settings, but even at the highest setting, it isn’t always bright enough for normal use.

The scope has some durability concerns, due to how cheaply it is made. There are plenty of examples of this sight breaking after very limited use.

At the end of the day, Ohuhu isn’t a rifle optics company. Vortex and Bushnell are. To expect the same quality as the other companies would be foolish. However, if you aren’t going to shoot your weapon much, and you are looking for a very inexpensive option, this optic may be decent for you. We would recommend spending the extra money for the Bushnell, but this might work

4. Holosun HS503C Paralow 133x54x72mm Circle Dot Sight

Holosun HS503C Paralow 133x54x72mm Circle Dot Sight

Holosun HS503C Paralow 133x54x72mm Circle Dot Sight

This sight from Holosun is an extremely basic red dot style sight. However, don’t let that turn you off from how high quality this sight is. This is actually one of our favorite red dot sights, despite its simplicity.

The optic measures 5.24 inches long, and weighs in at a tiny 4.25 ounces. As you can see, it’s a really small optic. It’s an internal reflex style red dot, which basically means that it’s a small tube with two lenses and the actual reticle is inside the tube, between the lenses. The dot is red, and the scope has no magnification.

When many people hear the term “red dot sight,” they are thinking about an external reflex sight. An internal reflex sight works pretty much the same, but the reticle and lights are all internal. In my opinion, these are more durable and reliable than external reflex sights, and I think they look a little better.

The pros of this optic are the ease of use, the solar power, and the durability.

When we say the ease of use, we mean in so many different ways. For starters, the optic is extremely easy to fire with. The reticle is extremely simple. It’s a simple dot reticle or a circle/dot combination, which is very easy to acquire targets and shoot accurately with.

The optic is also extremely easy to adjust, as most red dot style sights are. All you have to do is open the turrets, and use the simple mechanism to move the reticle. The clicks are easy to hear and feel, so you can get some peace of mind in your zero.

Another factor of this ease of use is how easy it is to install the optic. It has a simple cross bar style mount, meaning that you can easily mount it to either picatinny or weaver style rails.

The solar power also leads directly into the ease of use of the scope. Solar power is something not commonly seen in optics. For us, we really liked the feature. The reticle brightness adjusts for how bright it is outside, and when it’s bright enough to power the solar panel, the optic just stays on the entire time. As you can imagine, this makes it very easy to use.

The scope also has a battery backup, when it’s not bright enough out to use the solar power. The battery life is great, and the scope will automatically turn off after a wait period.

The cons of this optic are that it is pretty pricey, and it isn’t the most precise optic available. The price comes largely from the solar power. Similar optics without this feature will be much less expensive  (In my research). In our opinion, it’s worth the added cost though.

5. UTG 4.2" ITA Red/Green CQB Dot with QD Mount, Riser Adaptor

UTG 4.2" ITA Red/Green CQB Dot with QD Mount, Riser Adaptor

UTG 4.2" ITA Red/Green CQB Dot with QD Mount, Riser Adaptor

The UTG 4.2” ITA scope is extremely affordably priced, but also offers some decent features. While it isn’t the highest quality scope available, it definitely works for basic tactical uses and range shooting. We wouldn’t shoot competitions with it, but it is an acceptable optic.

The optic measures 4.17 inches long and weighs 9.8 ounces. Similar to the last optic, it’s a simple red dot with no magnification at all. However, this one differs in that it has a T-style reticle, which can be either red or green.

The pros of this optic are ease of use, and durability. Since this optic removes the solar power. While the optics of the previous sight are higher quality, this scope is decent. For basic shooting, it is more than acceptable.

The ease of use of this scope is extremely similar to the Holosun, so we won’t simply repeat the same features. However, this scope also has a quick detach base, so you just have to flip a lever to take it off of a picatinny-style rail.

As with the Holosun, this is a very durable optic. It’s waterproof, fogproof, and shockproof, and the internals are durable enough to withstand the recoil of multiple weapons. You can use this optic on shotguns and rifles with larger calibers as well.

The cons are that the reticle isn’t as easy to use, isn’t quite bright enough, and it is not that precise. I prefer the circle/dot combination reticle to the T-style. I think that the target acquisition is slightly slower, and it makes it harder to get a precision shot.

Speaking of the reticle, on bright days, it can be very difficult to see. The red dot works better than the green dot, but both are difficult to see when it’s really bright out.

Lastly, the adjustments of this optic are not that bright. If you’re shooting at longer distances, it’s going to be hard to be very accurate with this scope. The reticle is large, and you can’t adjust it that precisely.

6. Sig Sauer SOR52001 Romeo5 1x20mm Compact 2 Moa Red Dot Sight, Black

Sig Sauer SOR52001 Romeo5 1x20mm Compact 2 Moa Red Dot Sight, Black

Sig Sauer SOR52001 Romeo5 1x20mm Compact 2 Moa Red Dot Sight, Black

Last up, we’ve got an excellent optic from Sig Sauer. Similar to the previous two optics, this one is an internal reflex sight that is very compact in nature and has no magnification range.

It measures in at only 2.47 inches long and weighs only 5.1 ounces. As you can see, this is a truly tiny optic. It’s got a simple 2 MOA red dot style reticle, and really does have some great features. In terms of optical clarity, this may be my favorite on the list.

The biggest pros of this weapon, other than the extremely compact size, are the durability, MOTAC, and optical settings. As with all of the other optics, this one is very durable. However, Sig takes it to another level by guaranteeing that the optic is IPX-7 rated.

The MOTAC is a Sig creation. Essentially, the optic is motion activated. It will turn on when it senses motion, and turns off when it doesn’t. It’s that simple. It saves a lot of battery. I still prefer the solar power of the Holosun, but by a very slim margin.

Another pros of this optic is that it has two night vision settings to go along with eight normal settings. This is a much wider variety than the other optics mentioned.

Just like the other sights on this list, the red dot is large, and the adjustments aren’t that precise. It will be difficult for longer range shooting, but it is more than acceptable for CQB style shooting, and casual range use.

Buying Recommendations

Now that we’ve talked about the three scopes, lets make some buying recommendations.

Simply put, the Vortex is the best of the group.

If you are going to be shooting in low-light conditions or under night vision, the Vortex is your best bet. It will allow more light to pass through, and will be easier to see down.

For hunting, the Bushnell and the Vortex are both great options, due to how durable they are.

Conclusion

Hopefully our review of the best AR-15 optics was useful to you. When considering some of the things that we have mentioned, it should be way easier for you to select an optic for your weapon.

Buying a red dot for your AR can be an overwhelming experience. Choosing one of these, especially the Bushnell or the Vortex, will be a great choice for you.

For range shooting, either of these two options is a great choice. They are both good optics, but the Vortex may be slightly more accurate, especially at longer distance.
