Mossberg 590

Previous

The Mossberg 590 was, for many years, the standard issue shotgun for the Navy Seals.

Mossberg 590A1 with Speed Feed Stock and bayonet attached.

The Mossberg 590A1 is combat optimized Mossberg 500 series pump action shotgun.  It has several features that differentiate it from the standard hunting shotgun including:

  • 20” Counterbored Barrel (for firing slugs) with a ventilated heat shield.
  • 9 round full length magazine tube.
  • Speed feed stock with room for 2 rounds on each side.
  • Bayonet lug for an M7 or M9 bayonet.
  • Parkerized finish.

This shotgun is extremely reliable and, since 1987, has been the primary shotgun of the Navy SEALs and USMC.  However, it is currently being replaced by the Benelli M1014 semi-auto shotgun.  Also, being a lightweight 12 gauge it can have punishing recoil.

Receiver - Alloy.

Action - Pump Action.

Barrel - 20”.  Shotgun is 41” long and weighs 7 1/4 lbs.
