Caliber-Marked Non-Rotating Trigger/Hammer Sideplates & Screws ONLY

Upgrade or replace your existing KNS Non-Rotating Trigger/Hammer pin set's sideplates with our laser-engraved sets!

Easily & quickly identify your firearm’s chambered caliber at a glance with our laser-marked flat non-rotate sideplates. Important for newer shooters, range situations where multiple magazines & calibers are present,  or for pulling your rifle out of the safe after a few months.

These are the STRONGEST pins that can be produced and were designed to withstand the high impact of full and semi-auto 9mm, 5.56, and 7.62mm suppressed weapons. The pins are stainless steel. Black sideplates are black nitride treated. An absolute must-have for all M-16 owners. They will also protect your AR-15. Special anti-creep retainers prevent wear on your irreplaceable M-16 or AR-15 receiver.

Two sideplates & 2 Torx screws included. No modification to firearm required. Does NOT include trigger or hammer pins.

THE TORQUE SPEC ON THE SCREW IS 11 inch/lbs. MAXIMUM. We recommend 8INCH/LBS of torque. IMPORTANT NOTE: The external width of some AR receivers may vary in the trigger/hammer pin area depending on the manufacturer. The pins being slightly too long will not affect the function or performance.
