Mossberg Introduces MMR Carbine Semi-Automatic Rifle, a versatile AR-style platform configured with components desired by competitive shooters and tactical operators.

North Haven, CT – O.F. Mossberg and Sons, Inc., has designed the perfect multi-use modern sporting rifle, the Mossberg MMR Carbine in 5.56mm NATO/223 Rem.

Available in three versions, this semi-auto rifle features Mossberg’s new 13-inch handguard that combines a comfortable, slim profile with the versatile Magpul M-LOK system and a full-length top rail; Magpul MOE+ grip; Magpul MOE polymer trigger guard; 6-position adjustable or optional fixed length-of-pull (LOP) stock; 16.25-inch barrel with A2-style muzzle brake; and 30-round magazine (10-round versions are available). Mossberg’s newest version of the modern sporting rifle is ideal for hunting, competitive or recreational shooting and home defense use.

The standard features on the Mossberg MMR Carbine include a direct-impingement gas system for reliable, smooth operation; free-floating, button-rifled, carbon steel barrel with versatile 1:8 twist rate; removable rail-mounted, adjustable target sights (front sight is adjustable for elevation and rear sight for windage and elevation); single stage trigger; and black phosphate/anodized metal finishes for enhanced durability. A flat-top, full-length Picatinny rail provides for customization of your MMR with alternate sight systems or accessories. Stock options include a 6-position adjustable (10 1/2 – 14 1/4”) or fixed LOP (13 7/8”) combined with the slimmer profile, 13-inch handguard. Both feature a non-reflective black finish. The forward assist and dust cover are removed on this trimmed-down carbine.

Magpul MOE (Magpul Original Equipment) furniture enhances the modularity and comfort of the Mossberg MMR Carbine. The Magpul MOE M-LOK system has been incorporated into Mossberg’s new handguard for ease of attaching Picatinny rail sections and other M-LOK compatible accessories via the M-LOK slots. The MOE+ grip and trigger guard provide an ergonomic, hand-filling design with anti-slip texturing. The open core of the grip accepts optional Storage Cores for gear stowage.
