The barrel flange appears to be thicker on the "bottom" and won't go into the use receiver. The flange hangs up on the receiver. I thought all ump barrels were interchangeable? |
Not going to be the answer for solving it, but I just recently saw a video where someone replaced a bunch of parts on an Omega build to get it running, and it ultimately turned out to be the thickness of the ramp that was the issue. H&K UMP Clone Problems. How I got it 100% Reliable! |
