These are the Generation 2 pin sets. These STRONGEST pins can be produced and were designed to withstand the high impact of full and semi-auto 9mm and .223 suppressed weapons. 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 Allen wrenches included. No modification to the gun is required.
Features:
- The pins are stainless steel
- End retainers are black oxide
- Connectors have a phosphate finish
- An absolute must-have for all M-16 owners.
The .1555 dia. pin is for worn receiver trigger and hammer pinholes. 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 late-model 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 side plates. The only difference is cosmetic.
Instructions: The trigger pin is internally threaded on each end. Use a pointed tool to push out the old trigger pin and feed in the new one. Push out the old hammer pin about 1/8th" with a punch and finish pushing out with the new hammer pin. Install connectors over the ends of the hammer pin and align holes over the trigger pin. Install screws in the trigger pin. Do not over-tighten, snug will do. KEEP WELL OILED.
