AR-15 5.56/.223 24" black nitride bull upper assembly / 15" Mlok

AR-15 5.56/.223 24" black nitride modular bull upper assembly is a high-end firearm component and is offered exclusively by Moriarti Armaments. Custom made to order.

Specific attributes about the item: This upper assembly is compatible with the popular AR-15 platform. 5.56/.223 is the caliber of bullet that this upper can chamber. Both 5.56x45mm NATO and .223 Remington are accepted. It's based on 24" barrel, which is quite long, giving increased precision at the expense of maneuverability. Black Nitride indicates the type of finish on the assembly. Nitriding is a heat treating process that diffuses nitrogen into the surface of the metal, creating a case-hardened surface for improved durability and corrosion resistance. It comes with Bull Barrel - a type of gun barrel that does not taper down in diameter (getting thinner towards the end), like conventional barrels, which can help increase accuracy. Assembly is finished off with 15" MLOK handguard (protective cover around the barrel) - a type of rail interface system that allows for the direct attachment of accessories. This product is mainly used by shooting enthusiasts or competitive shooters who seek precision and high quality parts for their AR-15.
