Hee Hee..I've done it three times. Once practice and two for real.steelcore1964 said:I have done it once and it turned out pretty well, I still have two of my own Tabuk DMR rifles to weld as well. What state do you live in? If you are close to me you can come by and I will do it for free. I doubt if you will find anyone else that has done it 3 times that lives in the U.S.
