Key Features

• Bufferless DISSENT Operating System – Why it matters: Eliminates the need for a buffer tube, allowing a true side-folding stock without loss of function, keeping the rifle compact for transport or storage.
• 14.30-inch Threaded Steel Barrel – Why it matters: Provides a balance of velocity and maneuverability while accepting standard muzzle devices or suppressors; the steel construction ensures longevity under heavy use.
• Adjustable Gas Block – Why it matters: Lets you tune the rifle for suppressed or unsuppressed fire, reducing recoil and improving reliability across different ammunition types.
• Forward Non-Reciprocating Charging Handle – Why it matters: Stays in place during firing, reducing snag hazards and allowing quick, ambidextrous charging without moving parts interfering with optics or your hand.
• Side-Folding Stock with Adjustable Length of Pull and Cheek Riser – Why it matters: Offers a custom fit for different shooters and shooting positions, while the folding mechanism cuts overall length for easy packing.

Who It’s For

This rifle suits shooters who want the ergonomics and modularity of an AR platform but prefer the 7.62×39 cartridge and the convenience of AK magazines. It’s ideal for those who value compact storage, suppressor use, and a reliable gas system that doesn’t require a buffer tube.

Pros & Cons

• Pros: Bufferless design enables true side-folding stock; accepts common AK magazines; adjustable gas block for suppressed shooting; compact 14.30-inch barrel; non-reciprocating charging handle.
• Cons: The 7.62×39 cartridge can be more expensive than 5.56 NATO for practice ammo; aftermarket support for this specific platform is narrower than standard AR-15s.

FAQ

Does this rifle accept standard AK magazines?

Yes. The CMMG DISSENT MK4 is designed to accept AK-pattern 7.62×39 magazines. It uses a custom magazine well that interfaces with standard AK mags without modification.

Can I use a suppressor with the adjustable gas block?

Yes. The adjustable gas block allows you to reduce gas flow when using a suppressor, which helps keep the rifle cycling reliably and reduces blowback to the shooter’s face.

What is the overall length with the stock folded?

Per CMMG specs, the DISSENT MK4 with a 14.30-inch barrel and the side-folding stock measures approximately 26.5 inches with the stock folded. Extended, it reaches about 34.5 inches.

Is the charging handle ambidextrous?

The forward non-reciprocating charging handle is located on the left side of the handguard by default, but it can be moved to the right side for left-handed shooters. It is not fully ambidextrous out of the box but offers some adaptability.
