Pros & cons
What works

Trade-offs

About this product
The CMMG Dissent MK4 6.5 inch 32rd Midnight Bronze is an AR-style pistol built around CMMG's Compact Action and forward non-reciprocating side charger for reduced footprint and on-target charging capability. It features a 6.5-inch barrel with aluminum frame and polymer grip, finished in Midnight Bronze Cerakote, weighing 76 ounces with Picatinny optic footprint and ambidextrous manual safety.
What is the CMMG Dissent MK4 used for?
The CMMG Dissent MK4 is designed for practical range use, personal defense, and compact duty roles where maneuverability matters. Its 6.5-inch barrel keeps overall length to 19.5 inches collapsed, while the 32-round capacity ensures ample rounds on tap without frequent reloads during drills or defensive scenarios.
How does the CMMG Dissent MK4 compare to the Stevens 334 Rifle?
The Dissent MK4 offers superior close-quarters handling compared to the bolt-action Stevens 334 Rifle, with semi-auto operation and 32-round capacity versus the Stevens' 3-round internal magazine. However, the Stevens 334 in .308 Win delivers significantly better long-range accuracy past 200 yards due to its 20-inch barrel and bolt-action precision.
What does it weigh and what are the dimensions?
The Dissent MK4 weighs 76 ounces (4.75 pounds) with an overall length of 19.5 inches when collapsed and 22.8 inches extended. The 6.5-inch barrel and 5.5-inch M-LOK handguard create a compact profile that's 2.3 inches shorter than most 10.5-inch AR pistols while maintaining full accessory compatibility.
Who is this NOT for?
This pistol is not for shooters seeking long-range precision or those uncomfortable with NFA regulations surrounding short-barreled rifles. The 6.5-inch barrel limits effective range to approximately 100 yards with 5.56mm ammunition, and at $1820.99, it's a significant investment over entry-level options like the Stevens 334 Rifle.
What's in the box?
The package includes the complete Dissent MK4 pistol, one 32-round PMAG, operator's manual, and cable lock. Unlike some competitors, it does not include iron sights or a cleaning kit, requiring an additional $150-$300 investment for optic-ready deployment.
Is the CMMG Dissent MK4 worth it at $1820.99?
At $1820.99, the Dissent MK4 justifies its price through premium features like the TriggerTech AR-D trigger and Cerakote finish that outperform budget alternatives. For shooters needing compact reliability with accessory compatibility, it delivers value that mass-market pistols cannot match.

Frequently asked questions
- Is it compatible with standard AR-15 triggers?
- Yes, the Dissent MK4 uses mil-spec trigger components and includes a TriggerTech AR-D trigger from factory. The fire control group is compatible with any standard AR-15 trigger pack, requiring no modification for drop-in replacements.
- Does it fit in a standard pistol case?
- No, the Dissent MK4 requires a case with minimum interior dimensions of 24x9x4 inches due to its 22.8-inch extended length. Most pistol cases max out at 20 inches, so plan for a compact rifle case or larger tactical bag.
- How long does shipping take?
- Shipping typically takes 3-7 business days for in-stock items via FedEx Ground. All firearms ship to your local FFL dealer, where you'll complete the mandatory 4473 form and background check before taking possession.
- Can I return it if it doesn't fit my needs?
- Firearms sales are final once transferred through an FFL, per federal regulations. Ironclad Armory allows returns only for manufacturer defects within 30 days, with all returns requiring coordination through your transferring FFL dealer.
- Does this work with SureFire suppressors?
- Yes, the 1/2-28 muzzle threads are compatible with SureFire SOCOM series suppressors and most .223/5.56mm muzzle devices. The 6.5-inch barrel generates sufficient gas pressure for reliable suppressed operation with high-backpressure cans.
