Mossberg looked into the smaller details of the AR platform and engineered them for a world of difference in their MMR Semautomatic Rifles. A six-position adjustable stock with a length of pull from 10.5” to 14.25” fits most shooters. The ergonomically crafted Stark SE-1 deluxe grip and wide trigger battle hand fatigue. The pistol grip has a battery compartment for storing batteries to power a variety of shooting accessories. A Picatinny quad-rail free-float forearm/handguard holds accessories for total customization and is vented for optimum cooling of the barrel. The 16.25” carbon-steel, black phosphate, button-rifled barrel with a removable A2-style muzzle break has a 1:9 rate of twist for tack-driving accuracy.
