The Rise Armament AR-15 Ambidextrous Safety Selector enhances the functionality and reliability of your AR-15, AR-10, or AR-9 with its patent-pending design. The small parts, like the safety detent and spring, are self-contained, so you don't have to worry about losing them. Featuring a smooth 69-degree throw, it allows for quick switching between safe and fire positions. Designed for both left- and right-handed users, the interchangeable long and short paddles are easy to swap. Plus, the paddles are securely locked in with a detent, eliminating the need for screws and preventing them from loosening over time.
