ok im seriously going to go off on someone, just because hes creativly thinking outside of the box instead of using some hack job bolt cutters and rivets doesnt mean that hes going to have a bad ak. im building 5 this weekend in my buddys machine shop and i plan on welding everything! theyre 5 milled yugo underfolders and im sure that theyre going to turn out fine, actually the receiver will be twice as thick as a normal stamped kit and the welds will be 10 times stronger than rivets and since theyres more contact surface the rear receiver wont split at the rivet holes after 50,000-100,000 rounds. my buddy that im doing the build with welded one 6 months ago its build like a rock. Dont let these guys scare you. It wont be an origional all numbers matching low serial #, never fired collectors commerative edition "1 of 500" ak but no homebuilt is. If your building for quality and durability then go with welds, if you want an authentic piece of crap look then go with rivets, screws, ect. ect.!
