Gentlemen,
I have been trying to find a 2 stage trigger group for an older Colt AR-6520 carbine that uses LARGE PINS (0.170").
There don't seem to be any available. They are all listed as "out of stock, ETA of new stock unknown".
I wouldn't mind placing a backorder, but most of them claim a 12 to 18 month wait!
Wondering... could I take a trigger group and just ream the holes to 0.170? That is removing only 0.008" (radius) of metal. I looked at some trigger groups I have here at home and there seems to be WAY more than enough metal that enlarging the hole shouldn't be a problem.
Is the distance between the two pins the same as a "small pin" lower? Are they in the same location?
Any opinions or advice on this idea? Thanks!
