What Should You Consider Before Buying?

If you want to buy the perfect red dot sight for your AR 15, you need to look into a lot of features. A good red dot sight will have the perfect balance of all exclusive features.

Your AR 15 rifle deserves the best quality. That’s why you should always go for quality instead of quantity.

Want to know just what you need to look for? Just look at this list and you’ll know just what to do.

# Optical Coatings

The very first thing you need to consider is the optical lens quality. Optical lens quality hugely depends on the different coatings. High-quality lenses like ED or HD lenses would definitely be a plus point here. These lenses provide the best output in any situation for a AR 15.

Even though having extra fully multi-layer coatings are also a great option here. Fully multi-coated lenses improve the quality of your vision by decreasing lens reflections.

Extra features like waterproof, fog proof will ensure the durability of your red dot sight. Well, you do need to invest in a longer lasting red dot if you want to get the full experience, right?

# Brightness Adjustments

Another great feature you need to always look into before buying a red dot sight is the brightness adjustments. It’s actually the ability to adjust the intensity of the dot manually. The wider the range the better.

It means you can adjust the intensity of any lighting situation. It makes shooting in low light situations or at night time really easier. The best part is that you can adjust it back whenever you are shooting in broad daylight.

It would definitely come in handy while you are using your AR 15 for a short range hunting session.

Usually, most of the dot sights come with a wide range of adjustments. But still, you should always check out how many environments it covers. A lower adjustment range will cause serious issues while shooting in the dark.

# MOA Dot Size

The MOA Dot size refers to the size of the red dot. Most importantly, a bigger dot will defiantly ensure an easy target, to begin with. With bigger dot size you’ll be able to hit any target with your AR 15 without any problems or whatsoever.

You should always go for at least 2MOA dot size. Anything greater than this is undoubtedly a better choice but less than this will surely hurt your performance.

That’s why while choosing the perfect one go for 2MOA or more.

# Battery

AR 15 rifles are the most popular choice when it comes to longer hunting sessions. That’s why while choosing a red dot sight, you need to look for a longer lifetime. This can undoubtedly cause a huge deal if you don’t invest in a longer battery life. I’m sure you’ll be using your AR 15 for a longer session and this feature will defiantly be a lifesaver.

Most of the time shooters forget to turn off their dot sight and then end up draining excess battery life. That’s why a longer battery life will help you avoid any unnecessary situations and go on with a hunt without any issues. Pretty neat, right?

# Eye Relief

Having a proper eye relief or eye protection will surely help you in when you’ll be hunting for a long time with your AR 15. You don’t want to spend your money on it and then end up straining your eyes now, do you? You always need to look for comfort whenever you are looking for the best red dot sight.

Not to mention, this feature will be a lifesaver for eyeglass users. A greater eye relief feature or adjustable setting is what you need here. Always make sure your dot sight comes with it.
