So that we all know, DC Machine makes the majority of barrels that PSA is selling in todays market. Having some of these same problems I phoned a friend and took him my barrel. They checked it and I went over some of the concerns that I have seen here. The barrel was tested, like to the micron, along with checking the gas port. It was dead on. I get it that the information yall put out is making guns run but seeing first hand what they are doing over there I feel like the barrels are not the problem. They have a few fellows that shoot competition and we talked over a few fixes. He recombination was to switch over to rifle buffer setup. Just his 2 cents. Not knocking what yall are doing here.
