  • Mossberg 500

    Have an old Mossberg 500 20 gauge and not always but most times when I try to jack a shell into the chamber two shells pop up out of magazine.
    Any ideas? Thanks guys.

    Shell latch is most likely worn dirty or stuck, I would start there. look on They should have the parts you need. #42-#43 on their schematic

        Spray it out with some ballistol or gun medic. Cycle it several times. If problem persists replace worn parts.

        The 500 is in my opinion one of the most reliable pump guns ever made. Yes I own 870s too. The 500s are objectively more reliable, although they do start to rattle when they get old and worn out.

        *** I always wanted a welding stinger that looked like the north end of a south bound chicken. Often my welds look like somebody pointed the wrong end of a chicken at the joint and squeezed until something came out. Might as well look the part.
