These are the Mod 2 non-rotating trigger/hammer pin sets.
They are the toughest pins produced. We designed our pins to withstand the stresses generated by high-impact suppressed fire. Our trigger & hammer pins are stainless steel and our retainer sideplates are steel with a black nitride finish.
Our KNS non-rotating trigger/hammer pin sets prevent wear on your AR lower and prevent your pins from walking out of your receiver.
This kit includes an installation guide tool & 2 Torx wrenches. No permanent modification to your gun is required. These are the half-round style sideplates.
Torque spec for screw-tightening should not exceed 11 inch-lbs, 8 inch-lbs is recommended.
