AR-15 5.56/.223 16" M4 Carbine Upper w/ 15" MLOK Rail – Cerakote Finish | FDE, ODG, Grey | Moriarti Arms

Customize your build with a top-tier AR-15 5.56/.223 16" M4 Carbine Upper Assembly, available in your choice of Cerakote finish: Flat Dark Earth (FDE), Olive Drab Green (ODG), or Tactical Grey. This upper combines military-grade components with a modern lightweight 15” MLOK handguard for a rock-solid platform and enhanced style.

At the heart is a 16" M4 contour barrel, made from 4150 CMV steel, button-rifled with a 1:7 twist, and phosphate finished for long-lasting durability. It’s chambered in 5.56 NATO and accepts both 5.56 and .223 Rem. Completed with an A2 flash hider and crush washer on 1/2x28 threads, this setup is ideal for duty-grade performance.

The A3 flat-top upper receiver is made from 7075-T6 forged aluminum, black hardcoat anodized to mil-spec, and features M4 feedramps, forward assist, and a dust cover pre-installed.

You’ll also get a lightweight 15” MLOK free-float handguard, constructed from aircraft-grade aluminum and finished to match the selected Cerakote option. The sleek, slim profile supports accessory mounting without excess bulk.

Please Note: Due to the Cerakote process and material variations, color tone may vary slightly from batch to batch. We do our best to match components, but 100% color consistency is not guaranteed.
