Description
The 22 ARC cartridge was built to send light, high-BC bullets fast and flat, and the CMMG Dissent MK4 gives it a home that feels familiar in the hands but works differently under the hood. CMMG's bufferless Compact Action tucks the entire recoil system into the upper receiver, which means no buffer tube hanging off the back and a true side folding stock that makes this rifle genuinely packable. Fold it up for the truck or the pack, snap it open, and you're back in business with the same manual of arms you already know from any AR-15.
What Sets the Dissent MK4 Apart
Instead of a rear charging handle, the Dissent runs a forward-mounted, non-reciprocating side charger, so you can work the bolt without breaking your cheek weld or coming off target. The 16.1 inch medium taper barrel wears a salt bath nitride finish, is threaded at the muzzle, and comes capped with a CMMG Zeroed muzzle brake that keeps an already soft-shooting cartridge planted. An adjustable gas block lets you tune the system for your preferred load or dial things down when running a suppressor, and the Zeroed drop-in single stage trigger is a nice step up from the mil-spec units most factory rifles ship with.
Built for the Field and the Bench
The Dissent side folding stock adjusts for both length of pull and cheek height, so getting behind a magnified optic comfortably is easy. Up front, the M-LOK handguard with a full-length top Picatinny rail gives you plenty of room for a bipod, light, or whatever else your setup calls for. Receivers are machined and forged from 7075-T6 aluminum, and the whole package tips the scales at a very carry-friendly 6.7 pounds.

It ships with two 10-round magazines and is backed by CMMG's lifetime quality guarantee, so you can put it to work without a second thought.

Frequently Asked Questions
What is the 22 ARC cartridge good for?
The 22 ARC is a modern cartridge designed to push high ballistic coefficient .22 caliber bullets at speeds comparable to the 22-250, but from a semi-auto AR platform. That makes it a strong pick for varmint and predator hunting, long-range steel, and anyone who wants flat trajectories with very light recoil. It feeds from AR-15 size magazines, so the platform stays compact and familiar.
How does the bufferless action on the CMMG Dissent MK4 work?
CMMG's Compact Action houses the entire recoil assembly inside the upper receiver, so there's no buffer tube sticking out the back of the lower. That's what allows this rifle to run a true side folding stock and still fire with the stock folded or open. It keeps the familiar AR-15 manual of arms while trimming overall length for storage and transport.
Can I move the Dissent MK4's charging handle to the other side?
Yes. The forward-mounted charging handle on the Dissent MK4 is non-reciprocating and reversible, so it can be set up on the left or right side to match your preference. Since it sits forward on the receiver, you can run the bolt without lifting your head off the stock or losing your sight picture.
Is the CMMG Dissent MK4 22 ARC suppressor friendly?
It is. The 16.1 inch barrel comes threaded with a removable Zeroed muzzle brake, and the adjustable gas block lets you dial gas flow down for suppressed use. That tuning ability helps the rifle run cleaner and softer with a can attached, and you can open the gas back up for unsuppressed shooting.
