KNS Precision Non-Rotating Trigger/Hammer Pin .154" G2 – AR-15/AR-10

The KNS Precision Non-Rotating Trigger/Hammer Pin prevents pin rotation and wear in AR-15 and AR-10 lower receivers, a common issue with aftermarket triggers that can cause elongated pin holes and trigger malfunction over time. This Gen 2 design uses a captured side screw to positively lock the pin in place, eliminating the wallowing that degrades accuracy and trigger feel.

Machined from hardened steel with a corrosion-resistant black oxide finish, this .154-inch diameter pin installs easily without modification to the lower receiver. The side screw is designed to sit flush once tightened. Professional installation is not required, though a punch set and basic armorer skills are recommended. Sold individually—most installations require two pins (one for trigger, one for hammer).
