Mossberg 590RM Chisel Stock 12 Gauge SBS 11.5" Barrel - FDE - 10 Rd Box Magazine

Re-engineering high-capacity tactical shotgun design, the Mossberg 590RM Rotary Safety Selector 12 Gauge Shotgun (SKU 50229) utilizes the industry's first production double-stack magazine system ever developed for pump-action firearms. This revolutionary feeding mechanism provides significantly more efficient shell capacity relative to overall weapon length than traditional tube-fed or single-stack designs, housing a massive 10+1 round capacity behind an agile 11.5-inch barrel. Combining Mossberg’s legendary pump-action reliability with cutting-edge tactical enhancements, the 590RM is purpose-built for tactical security, personal protection, and high-volume defensive shooting.

At the center of its refined ergonomics is an innovative ambidextrous rotary safety selector switch that can be easily actuated without breaking the operator's firing grip. The shotgun features a Chisel Folding Stock Mount that allows the 8-position adjustable stock (12.5"–16.5" LOP) to fold completely flush along the reverse side of the receiver. Protected by a premium Cerakote polymer-ceramic receiver finish for superior corrosion and wear resistance, the 590RM incorporates a flat-profile trigger, a compact forend, an integrated barrel heat shield, an Accu-Choke system with a cylinder choke installed, and a top Picatinny rail optimized for red dot optics. Its heavy-duty double-stack magazine features stabilizing ribs, lever-style releases, hardened steel feed lips, over-molded steel shell ramps, and a removable floor plate for easy maintenance.
