So you just laid down a stack of green on the latest, greatest and most expensive rifle in the world.  Good for you, but realize that if you don’t have a world class scope or other optical device to go with your long gun (and an intimate understanding of how to properly use that sometimes enigmatic piece of hardware), you’ll never get to witness your rifle’s full potential.

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 calledXTI™ (Xpress Threat Interdiction™) AR-15 angle mount sights.
