Buyer’s Guide While Buying Optic for AR pistol

Best Optic For AR Pistol

Since there are no dedicated optics produced specially for the AR pistols, customers have to use the rifle optics and find the most suitable one.

After some research, it is not hard to determine which optics work best on AR pistols, but there are a few things to consider before buying.

1. Weight

AR pistols are made to be light, so any unnecessary weight will affect the firearm performance. Aside from the firearm, the optic used can also be why some users feel discomfort while shooting.

Even though going for a bigger objective lens might be good for a clear view, it also means that the optic is bigger and has a lot more weight.

That said, activities that require a lot of movement can be more difficult to perform with too much weight. Usually, an optic that is light and durable is more expensive, but it pays out in most situations.

2. Magnification

Unlike the standard rifle, AR pistols are only effective at close range. Although using the optic with magnification can help a lot with aiming, it is not important for the AR pistols.

Going for too big magnification is a waste of money that can be used for some modern feature. Most users prefer to have a maximum of 2x to 3x, which is more than enough for everyday use.

3. Battery

With so many products on the market, the battery life is something every firearm user should consider before buying. Some of the high-quality optics provide up to 5 years or even more in some cases.

That said, 5 years of battery life usually comes with more expensive products, so for most users, 3000 hours or regular use is sufficient. Also, some manufacturers offer a warranty for batteries, which is nice and important to consider before buying.

4. Durability

Depending on the specific activity, the durability of the optic can be a huge factor. For example, if you use the AR pistol only for the shooting range, you don’t need as much durability as someone who hunts with it.

On the other hand, traveling and moving through a hard terrain requires a high-quality optic that can withstand any impact or pressure. Basically, investing in durability depends on the usage of the firearm and optic.


Best Optic For AR Pistol

1. Should I get the optic with lens covers?

Yes always. The lens covers are something required for every optic, no matter the price or usage. Although the lens covers are not necessary for optics functionality, it protects your lens from damage and scratches.

Once the lens is damaged or scratched, it is no longer effective to use due to a lowered or decreased view. Even if your product does not include lens covers, buying a pair of covers is less expensive than new lenses or new optics.

Also, having covers means your product is likely to get dusted, so it is easier to maintain.

2. How many brightness levels do I need for my optic?

Brightness is important, especially during sunny days. Basically, it helps a shooter aim with a red dot and it provides a clear reticle view for any situation.

Having more than a few brightness settings allows easy adaptation and personal customization. When it comes to the brightness settings, the more is better in every scenario. Some products come with 11 or 12 settings, but you should get at least 8 as the entry point.

3. Is a red dot usable without the battery?

The answer is no. Without the power, the red dot is not visible. The battery is required for every red dot. It provides the necessary power to the optics, which allows you to use red tod and brightness settings.

If your battery has failed, you should replace it yourself or contact the manufacturer. Using your optic without the batterie is the same as the iron sight, which means you won’t be able to use a red dot properly.

4. Why would I need a waterproof and fog proof optic?

The waterproof and fog proof features allow a clear view during any weather condition. Users that mostly use an AR pistol for shooting range won’t feel a huge difference. That said, using your AR pistol in the open field will definitely be easier with these features. If you don’t have a clear sight, you won’t aim properly, which means you will have lower accuracy.


AR pistols should be used cautiously like any other firearm, no matter which activity it is used for. Finding a good optic provides a better aim for all targets since the iron sight has limitations.

The information within this article should help all users find the ideal optic for a specific activity. A high-quality optic definitely makes a difference for new users as well as more experienced ones.
