Used Mossberg 590A1 12 Gauge Pump-Action Shotgun 6-Shot with Adjustable Stock and M-LOK Forend

The Mossberg 590A1 is a pump-action 12 gauge built for duty-grade reliability and hard use. The receiver is marked M590A1, and the gun has a matte black finish, a ghost-ring style rear sight with a front post, and a 6-shot magazine capacity. It is a proven platform for home defense, tactical training and general-purpose use.

This one is set up with a 6-position adjustable collapsible stock and a pistol grip, so you can fit the length of pull to your frame, your gear or your shooting position. The M-LOK slotted forend lets you add a light, a vertical grip or other accessories without extra rails. The tang-free design and the classic Mossberg slide action make it easy to run.

It suits home-defense buyers, range shooters, and anyone building a dependable pump gun they can configure to their needs. If you want a proven 12 gauge workhorse with modern furniture, the 590A1 is a strong choice.

Condition: Used. In the photos the finish looks clean and even, with no visible wear, scratches or rust on the gun, and a yellow Mossberg barrel sticker is still in place. Light marks are visible around the bolt and ejection port.
