Mossberg 590A1 Short Barrel Shotgun

Short Barrel 590A1

The Mossberg 590A1 is the heavy-duty version of Mossberg's pump-action shotgun, built for military and law enforcement work. This short barrel version keeps the full-length stock but cuts the barrel down, so the gun is easier to move through doorways, vehicles and tight rooms. It suits home defense, patrol and duty use where a compact 12 gauge pump is wanted.

Features

• Pump-Action Operation — You cycle each round by sliding the forend back and forward, a manual action that runs reliably across a wide range of shotshell loads.
• Heavy-Walled Barrel — The 590A1 uses a thicker barrel than standard 590 models, so it holds up better to knocks and hard use.
• Ghost Ring Sights — A large-aperture rear ring on the receiver pairs with a protected front post, letting you look through the ring and put the post on target quickly.
• Ribbed Forend With Strap — The grooved forend gives a firm grip for fast pumping, and a nylon strap keeps your support hand in place under recoil.
• Top Tang Safety — Mossberg's safety sits on top of the receiver behind the action, where your thumb reaches it from either side, so it works for left- and right-handed shooters.
• Buttstock Shell Storage — Cutouts in the side of the synthetic stock carry spare shells on the gun, ready for a reload.
• Synthetic Stock With Textured Grip — The black polymer stock resists weather and wear, and a checkered panel on the grip helps keep your hand from slipping.
• Sling Attachment Points — A sling stud on the buttstock and a mount at the magazine tube cap let you fit a carry sling.
• Matte Black Finish — A low-glare black finish covers the metalwork and matches the black stock and forend.

Build and Ownership

The 590A1 is the Mossberg model built to the U.S. military's MIL-S-3443 shotgun standard, and the receiver carries the M590A1 marking. Because the barrel is shorter than 18 inches, it is a short barrel shotgun under the National Firearms Act, which means a buyer needs ATF approval and a tax stamp before taking possession, and state law may restrict ownership further. Check your local regulations before ordering.
