Key Things to Look For When Buying an AR-15 Red Dot Sight

Here are the key features to focus on when shopping for a red dot sight for your AR-15 Rifle:

  • Red dot brightness level

Not everybody likes their red dot reticle to be the same level of brightness. The time of day and available light also plays a role in the brightness you want your red dot reticle to be. So the more reticle brightness level settings you have on your red dot sight the better. That way you can customize your red dot sight’s reticle to exactly the way you like it under all different kinds of light conditions.

  • Adjustability

It does not matter how well your red dot sight shows up to point at a target if your AR-15 is not sighted in properly for accuracy. That is why it’s so important that your new red dot sight be able to be adjusted for accuracy. Look for a red dot sight that is highly adjustable for both windage and elevation. The more sensitive these adjustments are (called clicks for 1 turn on an adjustment knob) the better and more quickly you will be able to accurately sight in your AR-15.

  • Mounting

When shopping for a red dot sight you have to pay particular attention to the type of rail that it’s compatible with as far as mounting it goes. Not every red dot sight will fit on ever rail that can be mounted on an AR-15 rifle platform. So you have to make sure you know the rail mounting options for any red dot sight that you are thinking about purchasing. Most red dot sights will fit the more popular AR-15 mounting rails such as Picatinny and Weaver rails.

  • Construction

Not only does your red dot sight have to have optics that helps to improve your shooting accuracy but it also has to be built tough. Chances are that unless you shoot your weapon only in an indoor range you will be exposing it to some tough environmental conditions when you use it. Heat, dust, moisture and other harsh elements can significantly reduce your new red dot sight’s effectiveness or useful life.

Make sure any red dot sight you will buy will be made out of tough materials such as aluminum alloy tubing or heavy duty polymer plastics. They should also be sealed very well against moisture and it’s even better if the red dot sight you buy is waterproof.
