Most people when they outfit their AR 15 rifle platform will include some kind of scope in that mix too. After all, being able to identify and shoot a target at a greater distance enhances the performance of any weapon. There is just one problem if that scope fails or runs out of power you will be in trouble in a tactical situation. To that end, you should definitely have a backup sight (BUIS – backup iron sight) on your AR 15 weapon too. That is why we have chosen to review some of the best sight AR 15 choices.

What to Look For When Shopping For a Backup Sight (BUIS) for Your AR 15 Rifle Platform

Here are some characteristics to focus on when you are looking to purchase the best sight for your AR 15 weapon:

  • Stores out of the way

Since we are talking about a sight that is probably not going to be used as your main sight you don’t want it to be in the way. So buy a sight that when it’s attached to your rifle it is out of the way of such things as your fixed scope and adjustment knobs.

You need a little bit of a compromise here too. Even though you want your sight to store out of the way you still want to be able to get it working in a hurry if you are in a tactical situation. That is why most people choose spring loaded, flip-up sights to use as their backup sight on their AR 15 rifle platform.

  • Durable

Chances are you are going to bang your new AR sight from time to time. That is why you want it to be made out of durable material such as heavy duty polymer plastic or aluminum alloys.

  • Easy to sight in

Even though you cannot fine tune a sight like you can a scope you still will need to zero it in as best you can. So but a sight for your AR 15 weapon that has some adjustability built into it. Even metal sights you can usually adjust for such things as windage and elevation.

  • Tandem sights are best

Unless you are a gun expert who really knows their sights then it is best to get a matched pair of sights for your AR 15 gun. This simply means you want to buy both the front and rear sights as a package deal from the same company. That is the only way you will know the front and rear sights are compatible as far as sighting them in.

Here is a YouTube video that goes into a little more depth as far as backup sight selection for your AR 15 rifle:
