The Moriarti Arms AR-15 7.62x39 10.5” Pistol Upper Assembly offers the perfect compact power solution for your next AR-47 pistol build. Built around a precision-machined 4150 CMV barrel and topped with a slim cone muzzle brake, this upper assembly combines durability, performance, and visual appeal in one USA-made package.
The included 12” straight-cut M-LOK handguard gives extended reach and accessory mounting space, while maintaining a lightweight profile. A carbine-length gas system and low-profile steel gas block ensure smooth operation with the popular 7.62x39 round.
Compatible with all mil-spec AR-15 lowers, this upper is ideal for builders looking for AK power in an AR pistol format.
