ChopperGuy is a good friend of mine. He started with the 223Rem version, then had the bolt face opened up and fitted 7.62x39 bottom metal and magazines. You will have a hard time "shrinking" the bolt face on a 7.62x39 rifle. It shoots great, but he does not like the high scope mount. He had a fix for it, but check out his thread.
On a side note, Mike found that the 110gr Barns-X bullets were worthless on big Minnesota deer. The acted more like a FMJ or solid at 6.8spc velocities and now, like me, he uses 110gr ProHunters or 110Gr V-max bullets for animal shooting.
