The CSAT aperture, designed by Master Sergeant Paul Howe (USA, Retired), offers shooters a dual functionality sighting system. It features a conventional notch and post for a 7 yd zero, alongside a small aperture for a 100 yd zero. This design compensates for the 2-1/2 inches offset between these distances. Additionally, the rear sight is equipped with a same-plane large battle sight aperture, enabling users to switch to a broader field of view while preserving zero.

Compatible with generation 2-3 troy bases, generation 1 bases require an XS screw kit, incompatible with ozark armament micro flip-up BUIS
