The AR15 is known as America's favorite rifle, and iron sights have always had their place on the platform. The versatile MSR (Modern Sporting Rifle) is used for tactical, competition, hunting, and self-defense situations. AR15 Iron Sights are used as a standalone aiming system, as backups to an optic, or in tandem with a co-witness configuration. Fixed sights are available, but due to the uniquely customizable AR platform, most owners go for flip-up sights that will be compatible with other rail-mounted accessories.image

Although many shooters have opted for optics like a red dot, many see the utility in also mounting backup iron sights (BUIS). If your optic goes down for any reason, like dead batteries, malfunction, or breakage, you can immediately deploy flip-up sights (on both rear sights and front sights) to have an alternative sighting system. Commonly referred to as day-time and night-time peeps, these modern shooting apertures are great for normal shooting and close-quarter target acquisition. The products below are top-rated as the best AR Iron Sights by our customers who have purchased and used them in the field themselves.

We carry a wide range of Best-Rated AR15 Accessories to keep you in the fight, hunt, or competitive event. While you're shopping, don't forget to stock up from our huge Ammo selection!

Are flip-up iron sights accurate?

Flip-up iron sights are just as accurate as fixed rear sights and front sights. Many are adjustable for windage and elevation adjustments. Even when used in a 45-degree offset configuration, most shooters only need a little practice before they are able to take full advantage of the functionality of flip-up sights. Mounted properly, usually on a Picatinny rail and using a dab of Loctite, folding sights will retain accuracy over long periods without having to be zeroed again.

What are the best flip-up sights?

This usually comes down to a matter of opinion and personal preference but based on customer reviews, all of these have proven to be very popular with our customers:
