Okay guys, on the low end marker i used to ave, there was an o-ring on the end of the barrel that prevented it from vibrating loose, kept it straight and made it a little easier to get off. i've recently tried wacking an o-ring on my Kaner barrel back for my cocker, and the o-ring just kinda squishes out the side. when I look at the thread in the breech where the barrel goes, there is no space for an o-ring to slot into when the barrel is screwed in. Are all cockers like this? or is it just mine? also is there a place that will drill out or file out a space for the o-ring without cocking up the body? Thanks, Chris
