Mossberg 590RM 12 Gauge 18.5" 10+1 Pump-Action Tactical Shotgun - Stand-Off Barrel, Mag-Fed

The Mossberg 590RM is the magazine-fed variant of the Mossberg 590 pump-action shotgun, purpose-built for security and tactical applications. Chambered in 12 Gauge with a 2.75" chamber, the 590RM feeds from a detachable box magazine rather than the traditional under-barrel tube, giving the shooter faster reloads and flexible capacity options.

At the heart of this configuration is the Stand-Off barrel, an 18.5" breacher-style design with an integrated heat shield that extends over the barrel and magazine tube, providing extra protection for the shooter's support hand during sustained fire. The barrel carries a phosphate finish for corrosion resistance and ships with a Cylinder Bore choke installed in the Accu-Choke system.

The 590RM ships with one 10-round detachable magazine, giving the shotgun a 10+1 total capacity. The receiver is drilled and tapped for the optic or sight platform of your choice, with no factory sights installed. Overall length is 37" and the shotgun weighs 7.09 lbs.

The 5-position adjustable stock allows length of pull to be tuned from approximately 12" to 15.25", fitting a wide range of shooters and shooting positions. The stock and forearm are finished in Black.
