AR-10MM 16" Diverter Complete Upper Receiver w/ BCG and CH / Non-LRBHO – Moriarti Arms

The AR-10MM 16" Diverter Complete Upper Receiver delivers a streamlined, durable build for your next 10mm pistol-caliber carbine. Designed for shooters who prefer a traditional A2-style upper with forward assist and dust cover, this complete upper features a match-grade 10mm barrel topped with a diverter muzzle brake to direct blast forward—ideal for indoor ranges or close-quarters shooting.

Precision-engineered by Moriarti Arms, the upper includes a ramped BCG, 15" slim M-LOK handguard, and charging handle. The system operates on a simple blowback design and does not include LRBHO, offering a more classic AR feel with modern performance enhancements.
