CMMG 60AA90CCT Dissent MK4 | 6mm ARC | 16.10″

The CMMG Dissent MK4 is an AR-platform carbine built around the 6mm ARC cartridge and configured for controllable, flat-shooting performance from a compact 16.10″ threaded steel barrel. It ships with a CMMG Dissent side-folding stock, side charging handle, M-LOK handguard and a CMMG Zeroed muzzle brake, and includes ambidextrous controls and an adjustable gas block for suppressed or unsuppressed use. For optics under $1,000 that pair well with this platform, consider the Vortex Viper PST Gen II 3-15×44 — it provides the magnification and reticle clarity suitable for precision work with 6mm ARC. Typical applications for this rifle include precision target shooting and medium-range varmint or coyotes hunting.
