I have a Romy G kit, original barrel & trunnion but no barrel pin. Anyone know what size will work? Where to get one?
Thanks!
Yeah a 'standard' 7mm will work. You can either order one from the various AK suppliers (Copes, Centerfire, CNCWarrior, etc.) or just use a 7mm drill bit.

yup,you can use a drill bit shank.....if you dont have the correct size you can turn down a larger bit to spec with a angle grinder and a drill. or wait for one to come in the mail.........
I usually use a snap gauge to make sure of the size then order them from Ak Builder but you can go get a drill blank or even a drill and cut of the stem and use it for a pin... Just make sure you don't get a try stem or turned down bit...True Value has the SAE and the Numbered bits in stock simple 5 bucks and your done..... If you do cut one make sure you slightly chamfer the edge so its easier to install and use lube on the pin....
