KNS Gen 2 Mod 2 Non-Rotating Trigger/Hammer Pins – .154″
The KNS Precision Gen 2 Mod 2 non-rotating pin set is engineered for AR-15 rifles (including the FN 15® series) and compatible M16 platforms using .154″ trigger and hammer pins.

FAQ
Will these fit a standard AR-15 lower?
Yes. They are designed for AR-15/M16 pattern lowers that use .154″ trigger/hammer pins.
Do I need any special tools?
The kit includes a pin installation tool and two Torx® wrenches. No machining or permanent modification is required.
Why non-rotating pins?
They help prevent pin movement and receiver hole wear during high round counts, hard use, or suppressed fire.
What torque should I use?
Do not exceed 11 in-lb. We recommend about 8 in-lb for the sideplate screws.
