JP Enterprises Competition Trigger Group with Trigger, Hammer and Anti-Walk Pins AR-15 3 lb Single Stage

Kits include: Trigger, Hammer and 2 oversized Anti-Walk Pins. Kit will produce a 3 lb trigger pull and should be installed by a qualified gunsmith. Includes an instructional CD. Notes: Some Colt AR type rifles have been manufactured with hammer and trigger pins and holes which are approximately .176" in diameter. These are referred to as "large pin" Colts. This was done to eliminate the chances of someone putting M16 fire control parts into an AR receiver. This is not found in all Colt models, just some.
