Did something stupid, as usual... bought 2 Cetme/G3 receivers, thinking that they'd be fairly easy to put together. Learned the hard way about looking into construction of a kit before actually purchasing the whole thing. Long story short, the only thing I'm lacking is the barrel, but I don't trust myself with the assembly side of it all. I can't weld, and I have no metal-working equipment (much less the knowledge to use it). Anyone having a build party for one of these guns? Should I just sell the damn things and buy one already-made?
