Very low round count Mossberg 590 Shockwave for sale only, no trades. There’s a genuine problem with ALL Mossberg pump shotguns - if they get dropped only a couple of feet the pins for the shell lifter will get dislodged from the receiver which is relatively easy to get back into place so long as you see that BEFORE you work the action. If you try to work the action while the lifter is dislodged then you’re in sad shape because then it will require disassembly. I had a gunsmith resolve that issue where it will never happen on this Shockwave. See photos. $500 Not interested in any trades, must sell, make offer.
