Armaspec ST45 FDE Ambidextrous Safety Selector

The Armaspec ST45 is a short-throw ambidextrous safety selector in Flat Dark Earth. It moves 45 degrees from safe to fire instead of the standard 90. It fits AR-15 and AR .308 lowers.

A shorter throw means less thumb movement to get into action. Levers on both sides let either hand run it. It's a common upgrade for competition and duty rifles.

Check that your lower's markings and fire control group work with a 45 degree selector. Installation needs a punch to remove the old selector and reset the detent and spring. Compare the listed compatibility with the firearm in hand, since similar-looking components can differ by platform or generation. Browse more gun parts and accessories.
