Well, Bought the DPM parts kit a while back. Sent out the lower to be converted to semi-auto. Got it back. Now, need to weld up the receiver. I took a semester of MIG welding, and have come to the conclusion, I SUCK at it. Now, it may be something that I could get better at over time, but I have no opportunity at work or at home to weld that much. And, I don't want to attempt to weld it only to have to cut it apart and try again and again. With my current "skill" level, I ain't nowhere comfortable putting my face near anything I weld. Now, the receiver is in 4 pieces. My question is, would it be legal for someone to weld the first 3 pieces together (would still NOT be a complete receiver). I should be able to weld the last part (the very back end) of the receiver on, it's a pretty straight forward weld. Thoughts.
