Mossberg 590S Tactical 12 Gauge Shotgun 20" Barrel M-LOK Forend

The Mossberg 590S Tactical delivers unprecedented shell capacity flexibility in a pump-action platform, accepting everything from 1.75-inch mini shells to 3-inch magnums without modification. This tactical shotgun bridges the gap between traditional home defense and specialized applications requiring maximum ammunition versatility.

What Makes This Different

The 590S represents Mossberg's engineering breakthrough in shell compatibility, featuring a redesigned elevator and feeding system that automatically adjusts to different shell lengths. While standard shotguns require manual adjustments or struggle with shorter shells, the 590S seamlessly cycles 1.75-inch, 2.75-inch, and 3-inch shells in any combination. The capacity ranges from 7+1 with 3-inch shells to an impressive 13+1 with mini shells, providing tactical advantages unavailable in conventional pump guns.

Key Features

• Multi-shell compatibility: 1.75", 2.75", and 3" shells without modification
• Variable capacity: 13+1 (1.75"), 8+1 (2.75"), or 7+1 (3") rounds
• M-LOK compatible forend for accessories and tactical attachments
• Accu-Choke system with interchangeable choke tubes for versatility
• Optics-ready receiver with pre-drilled and tapped mounting holes
• 20-inch barrel with matte blued finish for corrosion resistance

The 590S excels across multiple scenarios from home defense to competitive shooting. The ability to load lighter-recoiling mini shells for training or close-quarters work, then switch to full-power loads for maximum stopping power, makes this shotgun exceptionally adaptable. Law enforcement and military personnel appreciate the tactical flexibility, while hunters benefit from the choke system's versatility for different game and ranges.
