OK folks, I have recently taken on the task of building an AMD-65 from a chopped up parts kit. I have worked on AKs in the past, but mostly in the more common areas of replacing and swapping internal parts and furniture. . . NOTHING like this. I also figured: "How hard can it be? I've built a dozen ARs." So I bought a parts kit, virgin barrel and 100% receiver. I began to "strip" the barrel (which there were 2 chunks of) of it's components, beginning with the far end. Pinns were knocked out and gas block and front sight base were removed by clamping the vise to the barrel and knocking them off with a larger diameter pipe. Next the rear trunnion was de-milled, by grinding off the rivet heads and drilling out the rivet from both sides of the trunnion. I was able to do this with a hand-drill, but I'd advise a drill-press.
