Armaspec ST45 Ambidextrous 45-Degree Safety Selector

Armaspec ST45 Ambidextrous Safety Selector

The ST45 represents a thoughtful refinement to the standard AR-platform safety selector. Rather than requiring a full 90-degree rotation to transition from safe to fire, this selector reaches the fire position at approximately 45 degrees. This shorter throw translates to faster safety disengagement—a meaningful advantage in dynamic shooting situations.

Key Features

• Ambidextrous Design: Operable from both sides of the receiver, accommodating left and right-handed shooters with equal facility
• 45-Degree Throw: Reduces manipulation time compared to conventional 90-degree selectors
• Smooth Operation: Engineered for consistent, friction-free movement
• Crisp Lockup: Positive detents ensure the selector remains firmly in position
• Flat Dark Earth Finish: Durable coating that resists corrosion and complements modern tactical aesthetics

Important Compatibility Note

This selector is designed specifically for AR-15 and AR-10 lower receivers that feature the correct "FIRE" marking positioned at the 45-degree point. Using this selector on receivers without proper 45-degree markings will result in misalignment between the selector position and the actual fire mode. If your lower receiver lacks the correct 45-degree markings, the FT90 selector is the appropriate choice.

Ideal For

Competitive shooters, tactical practitioners, and anyone seeking to optimize their AR platform's ergonomics and speed of operation.
