AR-15 5.56 NATO 10.5" Upper Assembly in OD Green with Mlok Handguard and Shroud – Moriarti Arms

Built for performance and style, the MORIARTI AR-15 5.56 NATO 10.5" MLOK Upper Assembly in OD Green delivers compact firepower with a custom cerakote finish. This upper is precision-machined to fit any standard AR-15 lower receiver, giving you a highly modular platform ideal for CQB setups, range days, or tactical builds.

The 10.5” 4150 CMV barrel is nitride-treated for durability, with a 1:7 twist rate optimized for heavier 5.56 and .223 Rem rounds. The carbine-length gas system ensures reliable cycling, while the Mini Reverse Thread Shroud provides a sleek finish with a 1/2x28 thread for muzzle device compatibility.

A lightweight 10” Mlok handguard, made from certified aluminum and Cerakoted in OD Green, offers ample mounting space for accessories. The A3 upper receiver is forged from 7075-T6 aluminum and includes a forward assist and dust cover, finished in matching OD Green Cerakote for a uniform, tactical appearance.

Note: Does not include BCG or charging handle. These may be purchased separately. Each unit is custom-built to order—please allow for additional cerakote processing time.
