The ST45 is an ambidextrous 45 degree safety selector for the AR-10/AR-15 platform. Instead of having a full 90 degree rotation to disengage the safety, this selector is set to fire at the around the 45 degree point. This allows the operator to flick the lever to disengage from safety. This safety selector is incredibly smooth and has a super crisp lockup. The levers are made from billet 7075-T6 Aluminum and are Type III black hard anodized. It is designed for firearms that have the correct "FIRE" markings on the receiver to match the 45 degree fire position of this safety selector.
