Just finished this build and took it to the range a few days ago and ran 60 flawless rounds through it.
It's chambered in 7.62x39. I used ASC 7.62x39 10 round mag that fed perfect. I even used my magpul standard 5.56 mags because I like the look better than the ASC mags and it would feed 6-8 rounds, so I kept it to 5 rounds and it fed perfect everytime.
Not 1 Fail to feed or fail to fire. Lets just say the boom was turning heads all the way down the firing line. It was louder than the 16" .308 AR-10's down the line.
The first shot out the pipe was kinda scary, but immediately put a smile on my face and made me giggle like a little girl.
Feel free to ask questions or tell me how I did or what I could improve.
Without further ado the PrOn:
