The Armaspec ST45 Ambi Safety Select FDE is a short-throw, ambidextrous safety selector built specifically for AR10 and AR15 rifles. Using a 45-degree throw instead of the traditional 90-degree rotation, it delivers a quicker, more natural transition from safe to fire while maintaining a smooth feel and crisp lockup. Aluminum levers paired with a steel core provide a balance of durability and low weight, and the Flat Dark Earth finish blends cleanly with modern FDE builds.

This selector is ideal for shooters who want faster, more intuitive control during range sessions, training, or competition without changing their grip or switching shoulders. It is designed for lowers marked for a 45-degree fire position and fits AR platforms chambered in 5.56/.223 and 7.62/.308. With its refined operation and thoughtful ambidextrous design, the ST45 reflects Armaspec’s focus on practical innovation in modern rifle accessories.
