Armaspec ST45 45 Degree Short Throw Ambi Safety Selector FDE

The Armaspec ST45 is a 45-degree short throw ambidextrous safety selector built as a drop-in upgrade for the AR-15 and AR-10 platform. Finished in Flat Dark Earth Cerakote over a rugged aluminum and steel construction, the selector delivers long-wearing corrosion resistance and a clean, low-vis look on a matched rifle.

Unlike a standard 90-degree safety, the ST45 shortens the throw to roughly 45 degrees from fire to safe, allowing faster, more positive manipulation between positions. The ambidextrous design adds a symmetrical lever on the right side, giving left- and right-handed shooters identical control. The ST45 incorporates a machined wear channel that allows the detent to escape from the detent hole, delivering a clean, positive engagement in both directions.

The ST45 installs as a direct drop-in replacement for the standard AR-15/AR-10 safety selector and is set to fire at the 45-degree position out of the box. A Torx key is included for installation. Made in the U.S.A., the ST45 is a popular upgrade for builders who want a clean ambidextrous setup without going to a billet lower or a full match-style selector.
