What’s Included
- Box/case included.
The Marinecote finish is applied to exposed metal surfaces for enhanced corrosion resistance, presented here in a matte silver tone on both the aluminum alloy receiver and the heavy-walled steel barrel. The receiver is marked "M590A1," and the ejection-port side carries "MOSSBERG, NORTH HAVEN, CT, U.S.A., 590®, 12 GA."
The 18.5 in barrel is clearly roll-marked "CHAMBERED FOR 2 3/4 AND 3 IN. SHELLS – 12 GA. – 18 1/2 IN. – CYLINDER BORE." This cylinder-bore, heavy-walled barrel aligns with the 590A1's reputation for durability while maintaining a compact overall length of 39.5 in.
This shotgun is set up in a factory 7-shot (6+1) configuration and weighs approximately 7.0 lb. It uses a front brass bead sight with no rear sight, keeping the sighting system simple and fast.
The furniture includes a black synthetic fixed stock with a rubber recoil pad and a synthetic M-LOK forend for accessory mounting. Front and rear sling swivel studs are installed for carry options, and the length of pull measures 14.0 in.
Made in the United States, this example corresponds to Mossberg SKU 50767. It reflects the core 590A1 features with the added Marinecote finish, combining rugged construction with environmental protection.
