CMMG Dissent MK4 22 ARC 16.10" Complete Upper - Sniper Grey

The CMMG Dissent MK4 Complete Upper is a dedicated 22 ARC upper assembly built for CMMG's compact, folding-stock Dissent Mk4 platform. It pairs a 16.10-inch barrel with a 1:7 twist rate that stabilizes a wide range of 22 ARC bullet weights for hunting, precision, and recreational shooting.

The upper receiver and handguard are machined from 6061-T6 aluminum and finished in a durable Sniper Grey Cerakote, giving the assembly light weight, corrosion resistance, and a clean, modern appearance. The handguard provides a stable mounting platform for optics and accessories, and the complete upper drops onto any compatible Dissent Mk4 billet lower receiver to finish the build.

Whether expanding an existing Mk4 build with a new caliber or assembling a new compact rifle around CMMG's folding-stock design, this CMMG Dissent MK4 22 ARC upper delivers modern 22 ARC performance in a dedicated, purpose-built package.
