CMMG Resolute 5.7x28mm 16.10" Armor Black M-LOK Complete Upper for AR-15

The CMMG Resolute complete upper group brings CMMG's 5.7x28mm Radial Blowback platform to any mil-spec AR-15 lower receiver. Built around a 16.10" barrel and finished throughout in CMMG's signature Armor Black, this complete upper is purpose-designed for the modern sport shooter and 5.7x28mm enthusiast.

At the heart of the system is CMMG's patented Radial Blowback operating system, engineered to reduce felt recoil and improve reliability compared to traditional straight-blowback pistol-caliber carbines. The new-generation CMMG 5.7x28mm magazines fit standard AR-15 magwells, giving you maximum modularity and compatibility with off-the-shelf lowers.

The slim EML 15 M-LOK Free-Float handguard features M-LOK attachment slots at the 3, 6, and 9 o'clock positions for mounting lights, lasers, foregrips, and other accessories without adding bulk. The barrel falls within the 16" to 16.99" range, providing carbine-length handling well-suited for a wide range of shooting applications.

This listing is for the complete upper receiver group only. A lower receiver, magazine, ammunition, and optic are not included and must be purchased separately.
