CMMG DISSENT MK4 22ARC 16.1 Black

Description

The CMMG DISSENT MK4 22ARC 16.1 Black is a factory-built AR-platform carbine that marries precision capability with a compact, foldable chassis. Built around the 22 ARC cartridge, this rifle delivers flat-shooting, wind-bucking performance from a 16.1-inch barrel, all while fitting into a package that stows and deploys quickly. It ships with a side-folding DISSENT stock—adjustable length of pull and cheek riser—plus a non-reciprocating charging handle and an M-LOK handguard. An adjustable gas block supports both suppressed and unsuppressed loads, and CMMG’s “Zeroed” components ensure consistent lockup and accuracy out of the box.

Key Features

• Side-Folding DISSENT Stock — Why it matters: Allows the rifle to collapse into a compact package for storage or transport while still offering a full-length cheek weld and length-of-pull adjustment for consistent shooting positions.
• Non-Reciprocating Charging Handle — Why it matters: Keeps the handle stationary during firing, reducing snag hazards and allowing a more stable cheek weld, especially when shooting from barricades or prone.
• Adjustable Gas Block — Why it matters: Gives you the ability to tune gas flow to match different loads or when running a suppressor, ensuring reliable cycling without over-gassing the system.
• M-LOK Handguard — Why it matters: Lets you attach lights, lasers, bipods, or grips exactly where you need them, without adding unnecessary weight or bulk.
• “Zeroed” Components — Why it matters: CMMG machines the bolt, barrel extension, and upper receiver as a matched set, which minimizes slop and promotes consistent headspace and accuracy shot after shot.

Who It’s For

This rifle is built for the shooter who wants a precision-oriented AR that doesn’t need a long barrel to reach out. It’s ideal for varmint hunters punching paper at 400 yards, for tactical competitors who value a compact platform, and for anyone who appreciates a factory-built gun that’s ready to run without aftermarket tweaks.

Pros/Cons

• Pro: The folding stock makes it easy to pack in a backpack or case without disassembly.
• Pro: The 22 ARC cartridge offers less recoil and flatter trajectory than 5.56, with better long-range performance than .223 Wylde.
• Pro: Adjustable gas block lets you dial in reliability for suppressed or unsuppressed use.
• Con: The 22 ARC is a newer cartridge, so ammo selection is thinner than 5.56 or .308, and it’s not as common on store shelves.
