The 18.5 in steel barrel uses a plain, cylinder-bore configuration for straightforward handling and a clean sight picture with the brass bead front sight. It accepts both 2 3/4 in and 3 in shells, adding flexibility across common 12 gauge loads.
The pump-action system is paired with a tang-mounted manual safety that includes a red fire indicator. Controls are simple and intuitive, with right-side ejection and a polymer trigger guard.
The receiver is aluminum alloy with a black finish, matched to a black steel barrel. The shotgun is outfitted with durable synthetic furniture, including a ribbed forend that offers a secure grasp.
A custom Hogue synthetic buttstock sets this example apart, providing a pebble-texture surface and a rear sling swivel stud. The length of pull is shortened to 11.5 in. The front sling attachment is a fixed ring on the barrel lug just behind the knurled takedown screw, and the fixed tubular magazine holds 5+1 rounds.
This 500A is marked Made in U.S.A., North Haven, Conn., underscoring its American manufacture and Mossberg heritage.
