THE TORQUE SPEC ON THE SCREW IS 11 inch/lbs. MAXIMUM. We recommend 8INCH/LBS of torque.
The .1555 dia. 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. The .1555 will not fit Jewell Trigger System.
The .170 size fits large pin Colts.
For Rock River National Match triggers use the .1555 only.
There is no strength difference between the Gen 2 and Gen 2 Mod 2 sideplates. The only difference is cosmetic.
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.
