XS Sight Systems, in collaboration with Lone Star Armory, introduced the XTI (Xpress Threat Interdiction) AR-15 angle mount sights at the 2012 SHOT Show. The XTI with XS Express Standard Dot Tritium front, and White Striperear, are back-up iron sights designed for quick acquisition in CQB situations.
The result of extensive field testing the XTI AR-15 Angle Mount prototypes were put through their paces by police firearms instructors, SWAT and patrol officers, as well as combat-seasoned former military professionals.
