7.5" 5.56 NATO AR-15 Suppressor Ready Upper Assembly – 9" M-LOK, Color Choice

Introducing the Moriarti 7.5" 5.56 NATO Suppressor Ready Upper Assembly, featuring an extended 9-inch M-LOK handguard, a distinctive 5-inch black faux suppressor, and a selection of anodized handguard colors.

Part of Moriarti's Suppressor Ready Series, this upper combines a compact 7.5-inch barrel with an extended, skeletonized handguard for a streamlined, modern appearance.

The 9-inch handguard is manufactured from 6061-T6 aluminum and features a 1.74-inch internal diameter, a steel barrel nut with aluminum clamp design, M-LOK accessory mounting, and QD swivel compatibility. Its extended profile creates the signature Suppressor Ready Series appearance, with the black faux suppressor extending beyond the handguard.

The upper features a 7.5-inch 4150 CMV barrel with a 5.56 NATO chamber, 1:7 twist, and pistol-length gas system. A black hardcoat-anodized 7075-T6 aluminum upper receiver complements the selected handguard finish.

Choose your color to personalize the look of your Moriarti Suppressor Ready upper assembly.
