Just received my new green mountain mini uzi short-barrel-rifle barrel. this thing is gorgeous and the quality and workmanship is absolutely top notch!!! i have a slight problem though.... the trunion restriction ring around the middle of the barrel seems to get caught up on the trunion itself. I thought that turning down a normal S barrel at the end was all a ll you needed to do to get the smg barrels to fit in a semi mini" although when i look at the barrel that came with my gun from vector# it doesnt have a trunion restriction ring# $ust a tiny bit of a step up that continues all the way to the back. this is how far my new green mountain barrel goes in%
this shot shows where the rubbing occurs on the center band%
this shot shows my original vector barrel on top and the new green
mountain on bottom% and this shot shows the big difference in overall diameter on the band part versus the tiny
