The 20-inch cylinder bore barrel is built from steel and uses a simple, durable brass bead front sight for fast alignment. There is no rear sight. The chamber accepts both 2.75-inch and 3-inch 12 gauge shells, offering flexibility across common load types.
The full-length, open-ended tubular magazine runs flush to the muzzle and includes a knurled clean-out cap with an integral front sling-swivel stud. Capacity is 6+1. Ejection is to the right side.
The receiver is aluminum alloy with a matte silver finish that matches the barrel. It is drilled and tapped at the top and fitted with plug screws. Dual action bars support smooth cycling. The safety is a top-tang, ambidextrous design.
Furniture is black synthetic in a pistol-grip-only configuration, paired with a ribbed polymer forend. This example has no bayonet lug or heat shield. Both the receiver and barrel are marked Model 590, and the receiver bears a North Haven, Connecticut, U.S.A. marking.
