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

The KNS Precision Gen2 Non-Rotating Trigger/Hammer Pin Kit is the original anti-walk solution for AR-15 and M16 lower receivers that use .154 inch diameter trigger and hammer pins. Marketed as the strongest pins KNS Precision produces, this Gen2 set is engineered specifically to handle the high-impact recoil of 9mm, .223, and 7.62mm builds, including suppressed rifles where factory pins tend to walk or rotate out under heavy use.

The non-rotating design locks the trigger and hammer pins positively in the lower receiver, eliminating the pin walking and migration that can cause trigger creep, hammer slip, or uncontrolled firing in high round-count and full-auto-rated platforms. Pins are finished in black nitride for wear and corrosion resistance, and the kit installs without any permanent modification to the firearm.

This Gen2 kit (the original KNS Precision anti-walk design, predating the Mod2 variant) ships with everything needed for installation: the two non-rotating trigger and hammer pins, an installation guide tool, and the two Torx wrenches required for proper fitment. It is a drop-in upgrade for any standard AR-15 or M16 lower with .154" pin holes and is particularly popular for pistol-caliber AR builds, suppressed rifles, and hard-use duty lowers.
