Gen 2 Non-Rotating Trigger/Hammer Pins 


Rise Armament recommends KNS pins with all their trigger groups.
These KNS pins were designed to withstand the high impact of full and semi-auto 9mm, .223, and 7.62mm suppressed weapons.

The pins are stainless steel. End retainers are black oxide. Special anti-creep retainers prevent wear on your M-16 or AR-15 receiver.

Pin installation tool and two Torx wrenches & screws included. No modification to firearm required.
The torque spec on the screw is 11 inch/pounds maximum; 8 inch/pounds of torque are recommended.
The .1555 diameter pin is for worn receiver trigger and hammer pin holes. Being non-rotational, further wear is eliminated. They will also fit new receivers and will remove the free-play in match triggers.
Note: The external width of some AR receivers may vary in the trigger/hammer pin area depending on the manufacturer. The  pins may be shortened a small amount by carefully filing material evenly from both ends of the pins. Them being too long will not affect the function or performance.
