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 referrend to as "large pin" Colts. This was done to make it more difficult to put M16 fire control parts into an AR receiver. This is not found in all Colt models, just some.
