XS Sights’ XTI AR-15 Angle Mount Back-up Iron Sights.

Sometimes optics break. And, sometimes you need to shoot things with an AR that are too close for you to use your optic, particularly if your optic has magnification. An option is to have open sights that co-witness with your optic but these can be distracting. They also work best with zero magnification optical sights. XS Sights has developed an ingenious solution that will work on any AR with a full length rail. These sights are called XTI™ (Xpress Threat Interdiction™) AR-15 angle mount sights.

XS Sights‘ Monte Long, a serious competition shooter, worked with Andrew Brady of Lone Star Armory to develop this sight system and I’ve been working with these sights on the new Mossberg MMR Tactical I’m impressed. Essentially, these sights – front and rear – clamp to your upper rail and extend slightly out to the right. On a pedestal from the base there’s a platform with a 45 degree angle. The front and rear sights are mounted on their respective pedestals. The rear sight emulates the rear sight used with XS Big Dot pistol sights; it’s a shallow V with a white line at the center. It is adjustable for windage. The front sight is a post with a rounded top and a 0.14 inch white circle surrounding a tritium vial. It’s adjustable for elevation.

These sights are fast to acquire and you can mount them to provide whatever sight radius best suits your eyes, and coincides the scope mounts for your optic. To use them all you need to do is rotate the rifle to the left 45 degrees and they are right there in front of your eyes. You can even zero these sights to compensate for close range offset. Suggested retail is $ 150.00. What a great solution to a true tactical problem and a must for a fight’n AR!
