The Armaspec ST45 Short-Throw Ambidextrous Safety Selector (brand part number ARM112-BLK) shortens the safety’s throw to a 45-degree arc, letting shooters flip from safe to fire with a faster, smaller thumb movement than a standard 90-degree mil-spec selector. Finished in black and built for both AR-10 and AR-15 platforms, the ST45 is fully ambidextrous, giving left- and right-handed shooters the same fast manipulation on either side of the receiver.
