The Armaspec ST45 is an ambidextrous AR safety selector that moves to fire at about 45 degrees instead of a full 90, so the safety comes off with a shorter, faster flick. Aluminum levers ride on a steel core for a smooth action and a crisp lockup. It fits AR-15 and AR-10 lower receivers, but it must only be used on a lower with matching 45-degree FIRE markings; for a lower without them, Armaspec recommends its FT90 full-throw selector. Finished in blue. Made in the USA.
