Design & Build Quality
Military-Grade Construction
The Mossberg 590R is built to meet U.S. Military specifications (Mil-Spec 3443G), ensuring extreme durability. Its heavy-walled barrel, aluminum receiver, and parkerized finish resist rust and wear, even in harsh environments.
Enhanced Reloading Speed (The “R” Advantage)
Unlike standard pump shotguns, the 590R features a relieved ejection port and receiver cutout, allowing shooters to insert shells directly into the magazine tube more efficiently. This design minimizes fumbling during reloads—a critical advantage in high-stress situations.
Ergonomic & User-Friendly Controls
- Tang-mounted safety – Easily accessible for left- or right-handed shooters.
- Dual-action bars – Smoother, more reliable cycling than single-action designs.
- Ambidextrous slide release – Faster unloading when needed.
Performance & Handling
Smooth & Reliable Pump Action
The 590R’s pump action is renowned for its butter-smooth operation, thanks to Mossberg’s dual-action bars. Whether firing buckshot, slugs, or less-lethal rounds, the shotgun cycles effortlessly with minimal effort.
Superior Sighting System
Many models come equipped with ghost ring sights, providing faster target acquisition than a simple bead sight—ideal for defensive and tactical use.
Versatile Ammo Compatibility
The 3″ chamber allows for a wide range of 12GA loads, from:
- 00 Buckshot (Home defense)
- Slugs (Hunting & barrier penetration)
- Birdshot (Training & competition)
