    Another 30 rounds expended today. Ran perfect again. No peening of the trunnion lugs. I'm gonna call it good. I will keep you posted.

    Update on the front trunnion. After about 200 rounds the right locking lug is starting to peen over. Just a tiny bit, and it may last forever, but it's not something I'm comfortable with. I have found out that it's one of those Polish V-Project civilian company CAST trunnions. I have ordered a comblock forged trunnion to replace it with.

I may just use the barrel from AK builder but would like to know how you did yours Looks Great.
    I built one with a 23mm Romy front trunnion and 23mm Bulgy .223 barrel and .223 feed plate. Used a Bulgy AK74 bolt/carrier/gas piston and vertical gas block, had no problem with it lining up.

    I used what I had on hand, a 45 deg gas block. The holes didn't line up, but I fixed that. Originally this had a romy 47 trunnion but I converted it to use AR mag, but wasn't happy with the right locking lug being so much smaller after converting, so that's when I got the crap trunnion, not knowing it was cast. Live and learn. Anybody need a weak trunnion for a low pressure or blowback build? EDIT for lol!
