The Armaspec ST45 is an ambidextrous, short-throw safety selector for AR-15 and AR-10 rifles. It moves to fire at about 45 degrees instead of the standard 90, so the safety can be flicked off faster, with smooth action and crisp lockup. Use it only on lowers with 45-degree FIRE markings; for standard lowers, Armaspec offers the FT90.
