1.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.

2. Bushnell Trophy 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

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

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

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.

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.


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.
