I have a new Mossberg 935 and when I take it apart for cleaning, I can't get the ammunition tube to unscrew! MAybe it's not called the ammo tube, but it's the tube where the plug is and you load rounds. Is this thing glued in too? I'm plenty strong, but I've applied my best kung-fu vulcan death grip to this thing and it won't budge. I feel like I'm going to damage it if I twist any harder. Is there a trick to getting it out? Thanks! Matt

Quit doing your kung-fu vulcan death grip. It isn't going to come out nor is it suppose to.
