Hello,

Can someone tell me if the pin hole sizes small (0.154") or large (0.174")?

I am thinking of picking up a new trigger. I would like for this to work with both a 5.56 upper and a Tactical Solutions 22LR upper.


Thanks,

slushpup

0.154 ...Colt had the only lower to my knowledge that had .170 pins. Be careful with your hammer selection when it comes to the Tac Sol upper. You wanna have a non notched hammer to avoid issues (ie. no rock river hammer, or 2 stage)

Large pin is like spotting Bigfoot- i've never seen one. However, my 1992 Colt Sporter may have had large, but I never noticed. RRA=Sm
