What’s Included
- Mossberg 590 Special Purpose Tactical 12 Gauge pump-action shotgun
The 590 series earned its reputation by completing the U.S. Navy’s rigorous NAVSEA endurance tests, and this Special Purpose Tactical variant carries that same pedigree. Its 20.5-inch cylinder-bore barrel is topped with a steel heat-shield to protect the shooter’s support hand during extended strings of fire.
An 8-shot magazine (7+1) teams with a 2.75- or 3-inch chamber to offer flexible load selection without sacrificing capacity. The quick-serviceable magazine tube includes a clean-out cap unique to the 590 line, speeding maintenance in the field.
A factory bayonet lug accepts standard U.S. M7 and M9 bayonets, adding capability for users who require it. The brass bead front sight presents a simple, snag-free aiming point that’s easy to pick up in low light.
The tang-mounted safety provides true ambidextrous operation, while the matte-blued aluminum receiver keeps weight down without compromising strength. Durable synthetic furniture with a ventilated rubber recoil pad rounds out a package built for hard use.
