OK, here goes. I bought 2 DPM parts kits last year. I got 2 kits, one live barrel, 19 drums, 6 mag pouches and the jig for a price I could not pass up. I sent my lower into SMGGUNS and had the semi-auto work done to the lower, bolt and the carrier in December, and just got it back last week. Now it is time to weld the receiver together. For starters, I need a 4-6" piece of round aluminium stock turned to a 1.024 diameter. Anybody here able to help out?????
