Armaspec ST45 Ambidextrous Safety Selector – AR-15/AR-10 – Black

The Armaspec ST45 Ambidextrous Safety Selector replaces standard mil-spec safeties with a true ambidextrous design that gives left-handed shooters—and right-handed shooters who prefer support-hand manipulation—full control over their AR platform. The 45-degree short throw reduces the arc of travel compared to 90-degree safeties, enabling faster transitions between safe and fire without overextending your thumb or breaking your firing grip.

Machined from steel with a black finish, the ST45 installs like a standard safety selector but adds a reversible lever on the off side. The short throw is optimized for competition and tactical use where speed matters, but remains positive and deliberate enough for hunting and general-purpose rifles. Installation is straightforward for anyone comfortable with basic AR lower receiver assembly—no gunsmithing required. The kit includes the selector shaft, both levers, detent, and spring.
