Moriarti AR-15, .300 AAC Blackout, 5 inch Upper Receiver MAR-300-5-4-A2. The Moriarti AR-15 300 Blackout 5 in Micro Pistol Upper Assembly is built for shooters who demand high performance in a compact platform. Engineered for suppressor compatibility, this upper features a durable 5-inch 4150 CMV barrel with a black nitride finish and a 1:7 twist rate to stabilize subsonic and heavier grain projectiles. Ideal for tactical builds or home defense, this short-barrel upper includes a slim 4-inch M-LOK free-float handguard for maximum modularity, and an A2 flash hider to minimize muzzle flash. The A3 flat top upper receiver is made from billet aluminum, anodized to MIL-SPEC standards, and comes equipped with a forward assist and dust cover. Note: This upper does not include a bolt carrier group (BCG) or charging handle.
