Hey yall. I've got a Mariner 590, and I love it for the most part, except that the magazine cap is extremely tight and can only be removed with a pair of pliers (with rubber on them of course). THE THREADS ON THE MAGAZINE TUBE AND CAP ARE NOT STRIPPED OR MESSED UP! The gunsmith I spoke with told me that what it appeared to him was that the piece inside the magazine tube holding the spring down had made the end of the tube slightly expand, making the cap extremely hard to screw on and off. He said that I should file the outside of the magazine tube around the rim to make it fit better. I am skeptical about filing on something that is already thin. Do yall have any better ideas?
