Barrel fit

[meric78]

Anyone ever had problems with the barrel not fitting easily into the body of your mag? I've tried several barrels now, mostly J&J (ceramic and 2-piece). Basically what happens is I oil both O-rings, go to slide the barrel in, and have to twist the barrel to get the first O-ring into the body. Once that's in, the second O-ring gets squeezed so much that it starts to stretch into the nubbin groove and if I try to push it in, the body ends up cutting O-ring, if it goes in at all. The solution was to remove the second O-ring, and as long as the first is oiled then it will go in with just a bit of effort. Is the lack of a second O-ring going to give me problems with the nubbin at some point (hasn't so far). Will having only one O-ring on the barrel reduce my gas efficiency? Are there any other unforseen issues that might arise? Thanks,

Although I'm not yet a pro at a mag, I have played with them , and saw no real problems with only one oring.
