Mossberg 590A1 12 Gauge 18.5" 6+1 Pump-Action Shotgun - M-LOK Forend - Optic Ready

The Mossberg 590A1 is the most durable pump-action shotgun in the Mossberg lineup, purpose-built to meet MIL-SPEC 3443G and adopted across U.S. military and law-enforcement service. This 50799 configuration delivers the duty-proven 590A1 in an optic-ready package: chambered in 12 Gauge with a 3" chamber, it pairs an 18.50" heavy-walled barrel with an M-LOK forend and a drilled and tapped steel receiver for direct optic mounting.

At the core is Mossberg's time-tested pump action, fed from a 6+1 magazine tube. The barrel is finished in non-reflective black parkerizing and topped with a simple bead front sight for fast, intuitive target acquisition. Mossberg's Accu-Choke system ships with a cylinder-bore choke installed, giving you immediate, no-modification utility for security, home-defense, and tactical applications.

Up front, the M-LOK forend provides positive mounting points for lights, lasers, and accessories without sacrificing the platform's legendary simplicity. The drilled and tapped receiver accepts optics directly and ships with a cover plate in place, so you can run iron sights out of the box and add a red dot or low-power variable whenever you choose. A fixed black synthetic stock keeps the shotgun balanced and maneuverable, and signature 590A1 touches - a metal trigger guard and metal safety button - round out the mil-spec package.

Weighing 7 lbs with an overall length of 37.75", the 590A1 50799 is a compact defensive shotgun equally at home on duty or in the home. Cylinder-bore choke is included.
