Finally got the Gonic barrel for my Contender carbine, nice looking barrel, with a stainless steel ramrod (209X.45 set-up). Problem is and it appears to be a major one, as I put the barrel onto the receiver, I noted the hinge pin didn't fit the new barrel. I figured no problem I'll just polish the hinge hole a bit for a better fit. The only problem is, is the barrel won't come off and won't pivot downward, it's stuck big time. Anybody else have this problem with a Gonic barrel? What's the cure? :x Sure went on easy, and without the hinge pin is sloppy, but that puppy just won't come off. RR :?
