SHOT Show 2018 – Mossberg 590M


The 590M is a box magazine-fed variant of the 590 shotgun. All the standard features of the 590 shotgun are present with the 590M (dual extrators, ambi safety, heavy-walled barrel, etc.), however the magwell features stabilizing ribs that engage with the magazine when loaded to ensure solid lock-up. The magazines for the 590M are manufactured by Adaptive Tactical, and come in 5, 10, 15, and 20-round capacities. They are a double-stack design, with hardened steel feed lips, overmolded grips, a self-lubricating polymer body, and an ASTM-A-228 music wire magazine spring.

The Mossberg 590M will be offered in both a standard and tri-rail model, the later of which includes a heat shield and ghost ring sights. Both models will come with a single 10-round magazine, and are currently in production.

    Does the shotgun feed from the tube as well? If so, which does it pull from first, magazine or tube?

    • Minn Kota says:

      The tube is there, but it’s purpose is to support the forearm and related functionality only. No rounds are stored there.

      Handled one at SHOT, and was impressed with the execution. This evolving over to semi-auto platforms will be fun!

    Good idea (arguably), it those Tapco/ UTG/ Mako-looking magazines are a dumpster fire. Simply hideous.

    Must have been designed by the same guy who bought the chainsaw grip was a good idea.

  3. jellydonut says:

    No, there is no magazine tube on these.

    Where would the lifter be? It would not work.

  4. Bradkaf308 says:

    If it works, a shockwave version please. Why? Because I’m in Canada & it’s no biggy to have a short brl shoty. I’ll just put a butt on it.

  5. Mark says:

    I’d rather see a magazine systems on the 930.

    That bad larry, would be a trench clearing machine if you could slam fire it like the old WW1 1897winchester.
