I'd like to get a 7.62x39 rifle built, and I'm very interested in the gun having a bit of a "RPK" flavor about it. I'd specifically like to use a RPK or bulged trunnion and 1.5mm stamped receiver.
The receiver doesn't appear to be much of an issue, but how do I source the trunnion? Everything I see is of the "standard" front trunnions, and not the bigger RPK ones.
