These are the Gen JJ pin sets. They are the STRONGEST pins that can be produced and were designed to withstand the high impact of full and semi-automatic 9mm and .223 suppressed weapons. They will also fit the .308 AR rifles. The pins are stainless steel. End retainers are steel with a stainless steel finish. 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. Pin installation tool & 2 Torx wrenches included. No modification to firearm required.
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. Our pins may be shortened a small amount by carefully filing material evenly from both ends of the pins.
The being too long will not affect the function or performance.
PLEASE READ the INSTRUCTIONS!!! Over-torquing the screws can cause damage to these side-plates.
