Loose barrel

[Hobbyman2007]

Would think that would make the barrel hard to remove, and prone to galling the receiver.... Is there no room for additional setscrews in 2 or 3 planes?....

Good point Bob. Didn’t even think of having to remove the barrel. Another thing to think about is air leakage , what about groving the barrel and installing some 90 Douro or harder orings .

I don't know anything about how the barrel is sealed up in that gun.... Some guns have the transfer port sealed directly to the barrel, not the receiver.... I have one gun with no "seal" between the receiver and barrel, but the setscrew pushes the barrel down against the port in the receiver and it doesn't leak.... If there was a large diameter difference, that wouldn't likely work, though....
