Mossberg MMR Tactical 5.56 NATO AR-15, 16 in Threaded Barrel, Free-Float Aluminum Handguard, Black
This early-production Mossberg MMR Tactical stands out with its slick-side upper that omits the forward assist while retaining a dust cover and brass deflector, a configuration noted on the barrel rollmark from Eagle Pass, Texas, USA. It features a 16-inch carbon steel, button-rifled barrel with 1/2x28 threading capped by an A2-style birdcage, a free-float aluminum handguard with continuous top and full-length bottom rails, and forged aluminum receivers with a flat-top Picatinny rail. The bore condition is excellent, and it feeds from standard AR-15 pattern magazines.

The MMR Tactical uses a direct-impingement, semi-automatic system with a carbine-length gas setup. Its 16-inch-class carbon steel barrel is button-rifled with a 1:9 twist and threaded 1/2x28, paired with an A2-style birdcage for compatibility with common muzzle devices. The slick-side upper lacks a forward assist yet includes a dust cover and brass deflector.
The free-float aluminum handguard provides a continuous top rail and a full-length bottom rail with ventilated sides for heat dissipation. A flat-top receiver with an integral Picatinny rail allows straightforward mounting solutions. The receiver set is forged aluminum with a black anodized finish for durability.
Furniture includes a 6-position collapsible stock and a finger-grooved polymer pistol grip for a secure hold. Controls are familiar, with a manual safety and a standard charging handle. The rifle feeds from AR-15 pattern magazines and is listed at 30+1 capacity with a 30-round magazine and 40+1 with the included 40-round PMAG.
This example is an early-production MMR Tactical configuration noted for its Eagle Pass, Texas barrel rollmark. The overall condition shows normal handling, while the bore is excellent with sharp rifling, supporting strong on-range performance.
