5" 5.56 NATO Micro ARP Shark Flag Upper Assembly – Slick Billet, 4.2" M-LOK
The Moriarti 5" 5.56 NATO Micro ARP Shark Flag Upper Assembly combines distinctive custom accents with a compact, streamlined AR-15 upper configuration. Featuring a slick-side billet upper receiver, an updated 4.2-inch M-LOK handguard, and coordinating American flag-themed dust cover and charging handle, this upper brings a recognizable custom appearance to Moriarti's Micro ARP Series.
The slick billet receiver features a clean, modern profile without a traditional forward assist. Its black finish complements the geometric M-LOK handguard and the subdued black-and-gray American flag detailing.
Built around a 5-inch 5.56 NATO barrel, the assembly retains the compact proportions of the Micro ARP platform. The updated 4.2-inch free-floating M-LOK handguard provides a streamlined appearance, while shark muzzle device completes the configuration.
Unlike a standard black upper assembly, the Shark Flag model features matching flag-themed details on both the dust cover and charging handle.
