KNS Precision Gen ST Non-Rotating .154 Trigger/Hammer Pin Kit AR-15/M16 - Red

The KNS Precision Gen ST Non-Rotating Trigger/Hammer Pin Kit is engineered for mil-spec AR-15 and M16 lower receivers, replacing the factory trigger and hammer pins with a non-rotating design that prevents the pins from walking out under the high-impact, short-bolt cycling of suppressed fire, full-auto fire, and hard-recoiling 9mm, .223, and 7.62mm AR-style rifles and pistols.

Each pin is machined from stainless steel with a red finish for quick visual identification and corrosion resistance, and is sized to the standard .154" diameter that fits mil-spec AR-15/M16 lower receivers. The kit includes the trigger and hammer pins plus coated retaining screws to lock them in place. The non-rotating geometry keeps the pins indexed against the lower receiver, eliminating the rotation and play that allows factory pins to drift during sustained fire.

Built to withstand the punishing recoil and bolt-cycling forces of full and semi-auto fire, the Gen ST pins are a drop-in upgrade for any standard AR-15/M16 lower using mil-spec small pins.
