The Mossberg 590R is a modern pump-action shotgun built on decades of proven 590 reliability, now reimagined for shooters who want AR-platform ergonomics without sacrificing shotgun performance. This 12 gauge 3" chamber model holds 6+1 rounds and pairs a full-length heat shield barrel with an adjustable synthetic stock and Magpul grip—making it equally at home in a defensive scenario, tactical course, or hunting situation where modularity and quick target engagement matter.
What sets the 590R apart is its AR-style controls: an ambidextrous rotary safety selector, Mil-Spec compatible stock receiver that accepts standard AR adjustable stocks, and a Picatinny rail on top ready for optics. The 18.5" Flat Dark Earth Cerakote barrel integrates a full-length heat shield, so your support hand stays comfortable even after extended shooting. The Flat Dark Earth receiver matches the barrel for a cohesive, professional finish. Traditional 590 internals—dual extractors, twin action bars, positive steel lockup—deliver the smooth, reliable cycling that made the 590 an institution.
The enlarged loading port and exposed follower speed up reloads under pressure. Two QD ports on the stock give you flexible accessory mounting. The five-position adjustable stock and interchangeable recoil pad let you dial in fit for your frame and shooting style. If you're coming from AR rifles or want shotgun controls that feel familiar, the 590R bridges that gap without compromise.
