Micro ARP – Gradient Series

5" 5.56 NATO Micro ARP Gradient Series Upper Assembly – Side-Cut Billet, 4" M-LOK

The Moriarti 5" 5.56 NATO Micro ARP Gradient Series Upper Assembly brings custom styling and distinctive machining together in an ultra-compact AR-15 upper configuration. Featuring a lightweight side-cut billet upper receiver, a 4-inch parallelogram-pattern M-LOK handguard, and coordinated Cerakote finishes, this upper offers a striking alternative to traditional black AR-15 assemblies.

The Gradient Series features a selection of custom Cerakote gradient colors, complemented by a matching Cerakote tactical charging handle, dust cover, and five-port A2-style muzzle brake. Each color combination creates a coordinated appearance that highlights the billet receiver's distinctive side-cut profile and the geometric design of the handguard.

Built around a 5-inch 5.56 NATO nitride barrel with 1:5 twist and 5R rifling, this Micro ARP upper features a micro-length gas system and .750-inch low-profile gas block.

Designed around the familiar AR-15 platform, the Moriarti Gradient Series combines a distinctive billet design, premium custom finishes, and coordinated components in one recognizable Micro ARP upper assembly.
