If you run an AR platform rifle and want faster target engagement, the Armaspec ST45 45-degree short throw ambidextrous safety selector cuts the mechanical distance between safe and fire. Unlike a standard 90-degree safety that requires a full rotation to disengage, the ST45 reaches the fire position at 45 degrees—giving you a quicker, more intuitive flick when you need it. Built with aluminum levers and a steel core, it's designed to work smoothly on both AR-15 and AR-10 rifles and comes finished in practical Flat Dark Earth (FDE).
The ST45 is engineered for speed without sacrificing control. The lever operates with a crisp, reliable lockup, and the shorter throw means less wrist movement and faster transitions during rapid shooting or competitive scenarios. Because the safety is ambidextrous, both right- and left-handed shooters get the same ergonomic advantage—no fumbling for a selector positioned for the other side of the gun.
One critical detail: the ST45 is designed to work with receivers that have fire markings at the 45-degree position. If your lower receiver has standard fire markings elsewhere, you'll need Armaspec's FT90 instead. Always verify your receiver's markings before installation to ensure safe, proper operation. Made in the USA, it's a no-nonsense upgrade for anyone serious about improving their platform's handling.
