Mossberg 590A1 Magpul 12 Gauge, 20 Inch Shotgun

Description

We stock the Mossberg 590A1 as a pump-action 12 gauge shotgun configured with a 20 inch heavy-walled barrel and Magpul furniture. Its setup includes XS ghost ring sights, a black Parkerized finish, and a fixed Magpul SGA stock with MOE forend. This configuration suits structured range and training use where a straightforward manual of arms and durable, service-oriented components matter.
