Greetings: Joe (givette) here: What size trigger/hammer pins? My Colt AR-15 SP1 was manuf. 1974. If the DOM isn't enough info to determine what size pins I have, then what size drill bit should I insert into the side of the lower receiver to determine if the pins are large or small? Tks in advance. Joe (givette)PS..gambled and ordered a large-pin parts replacement kit. Hope I dont have to send it back.
