AR-15 Resolute 100 16" Complete Upper Receiver 9mm Black

A Perfect Upper Receiver for Your 9mm Carbine

Thanks to the growing popularity of pistol-caliber carbines, CMMG rolled out a reorganized line of 9mm upper receivers that are compatible with the company's unique 9 ARC magazine system. When used with one of the company's Resolute AR-15 9mm upper receivers, the 9 ARC system allows users to feed 9mm through standard-sized AR-15 magazine wells.

The CMMG Resolute AR-15 upper receivers are available in three tiers: the Resolute 100, 200, and 300. All of the upper receivers are complete units, shipping with a charging handle and a bolt-carrier group, unlike many other upper receivers on the market. The uppers also include a 16.1-inch, medium-taper barrel machined from 4140CM steel. However, there are differences that are important for the consumer.

The 100 Series CMMG Resolute upper receivers are equipped with an A2 flash hider, mil-spec charging handle and an RML15 M-Lok handguard. The Resolute 200 Series includes an SV Muzzle Brake instead of the standard A2 flash hider, and the Resolute 300 Series swaps out the mil-spec charging handle for an ambidextrous design from CMMG while also including the SV brake.
