The Mossberg 590R is a modern tactical pump-action shotgun built on a platform that respects the reliability of proven pump designs while introducing features that make it equally at home on the range, in a defensive role, or hunting. This 12-gauge fires 3" shells and holds six rounds in the tube plus one in the chamber, giving you a seven-round total capacity. The 18.5" barrel comes with an integrated heat shield to manage barrel heat during sustained use, and the entire gun is finished in Flat Dark Earth Cerakote—both barrel and steel receiver—for a cohesive, professional appearance that resists corrosion.
What sets the 590R apart from older pump shotguns is its AR-platform ergonomics. A rotary safety selector (ambidextrous, like an AR) replaces the traditional crossbolt, and the stock accepts standard mil-spec buffer tube adapters, meaning you can swap in your choice of commercial AR stocks if you want to customize fit and function. This example comes with a Black Magpul MOE+ grip and a 5-position adjustable synthetic stock with an interchangeable recoil pad, so you're not locked into one setup. The forend is redesigned for cleaner manipulation, the loading port is enlarged and beveled to speed reloads, and dual extractors plus twin action bars ensure smooth, reliable cycling.
The top of the receiver wears a Picatinny rail optimized for AR-style optics, making it straightforward to mount a red dot, scope, or other sight system. Two QD mounting ports on the stock adapter give you quick-detach options for slings or other attachments. This is a shotgun that respects tradition—solid pump-action fundamentals with dual extractors and positive steel-to-steel lockup—but speaks the modern tactical language that many shooters already understand.
| Gauge | 12 |
| Chamber | 3" |
| Capacity | 6+1 (tube + chamber) |
| Barrel Length | 18.5" with integrated heat shield |
| Barrel Finish | Flat Dark Earth Cerakote |
| Receiver Finish | Flat Dark Earth Cerakote steel |
| Stock | Black AR mil-spec adjustable synthetic, 5-position, interchangeable recoil pad |
| Grip | Black Magpul MOE+ |
| Sights/Rail | Top Picatinny rail (optics-ready) |
| Chokes | Accu-Choke system |
Yes. The stock base is mil-spec compatible and accepts standard buffer tube stocks. The Magpul MOE+ grip shown comes installed, but you can swap it for other AR-platform grips if you prefer a different angle or material. This modularity is one of the 590R's key advantages over traditional shotguns.
The 590R uses the Accu-Choke system. The specific choke tube configuration depends on your intended use—consult Mossberg documentation or your retailer for details on which choke is pre-installed.
Yes. The rotary safety selector is ambidextrous, allowing left- and right-handed shooters to manipulate the safety without repositioning their grip, following AR-15 ergonomic conventions.
The top Picatinny rail is optimized for AR-style optics such as red dots, low-power variables, and other compact sight systems. Standard Picatinny-mount accessories will work; avoid bulky or offset optics that may interfere with the heat shield or forend.
