Product Information

These tool steel Hammer and Trigger Pins work to remove the slop between the trigger, hammer and the receiver. Pins feature Allen heads for easy tightening and are finished in black oxide. Trigger and hammer may have to be reamed for a perfect fit. No modifications to receivers are needed.
AR-15 Hammer and Trigger Pin Dimensions:
  • 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.
  • All other AR type rifle manufacturers have stayed with the .156" diameter hammer and trigger pins and holes, or "small pin" which is the same spec used in all military M16 rifles.
  • Measure your pins or the holes in your lower receiver to determine if you have a "small" or "large" hole Colt® AR
