CMMG RESOLUTE MK4 16.1 ARMOR BLACK

Description

We stock the CMMG RESOLUTE MK4 as a semi-automatic AR rifle configured for recreational shooting and range use. Its 16.1-inch barrel, direct impingement operating system, and Mk4 platform establish the basic layout, while the EML15 handguard provides Modular Lock (M-LOK) attachment slots. This model has a black Cerakote finish and includes one 30-round magazine.

Key Specifications

• The rifle uses a semi-automatic, direct impingement operating system for a familiar AR platform configuration.

• The upper receiver is formed from billet 6061-T6 aluminum, while the lower receiver uses forged 7075-T6 aluminum.
• The rifle has a black Cerakote finish for its exterior surfaces.
• The CMMG EML15 handguard provides M-LOK (Modular Lock accessory mounting) slots at the listed positions.

The Mk4 platform combines a billet 6061-T6 aluminum upper receiver with a forged 7075-T6 aluminum lower receiver. The EML15 handguard places M-LOK slots at the 3, 6, 9, and 12 o’clock positions, while the absence of a full-length Picatinny section keeps the handguard layout focused on those mounting areas. We would point this configuration toward shooters who want an AR rifle with a 16.1-inch barrel, a Cerakote exterior, and included magazine. The CMMG RESOLUTE MK4 keeps those design choices together in one complete rifle.
