KNS Precision Gen2 Mod2 Non-Rotating .154" Trigger/Hammer Pin Kit AR-15/M16 Black

The KNS Precision Gen 2 Mod 2 Non-Rotating Trigger/Hammer Pin Kit is a precision upgrade for AR-15 and M16 lower receivers, purpose-built to solve one of the platform's most persistent issues: pins walking and rotating under hard use. This kit includes a matched pair of .154" diameter pins for the trigger and hammer positions, held rigidly in place by KNS Precision's signature external side plates and anti-creep retainers.

Constructed from hardened stainless steel and finished in a corrosion-resistant black nitride, these pins are engineered to be among the strongest KNS Precision produces. They are designed to absorb the punishing impulse of full- and semi-auto fire in 9mm, 5.56/.223, and 7.62mm suppressed builds without the pins drifting or rotating in the receiver. That stability helps protect valuable select-fire and semi-auto lowers from wear caused by loose, spinning pins.

Installation requires no permanent modification to the firearm, making this a true drop-in upgrade. The pins slot into the standard AR-15 lower pin holes and lock against rotation through the side plate geometry, so shooters gain long-term reliability without altering their lower. The Gen 2 Mod 2 pin kit is a straightforward upgrade for any AR builder who expects their trigger and hammer pins to stay exactly where they should.
