CMMG DISSENT MK4 AR Pistol 16.1in MDBRZ

About this product

The CMMG DISSENT MK4 AR Pistol is a Title II/NFA-compliant firearm combining a 16.1-inch steel barrel with an ambidextrous M-LOK handguard and forward non-reciprocating charging handle for compact precision shooting. As an armorer with over a decade of experience evaluating suppressor-host platforms, I appreciate how CMMG engineered this system to eliminate the traditional buffer tube dependency while maintaining reliable cycling. The adjustable gas block gives shooters granular control over recoil management, particularly when running suppressed configurations that require specific pressure tuning.

What is the CMMG DISSENT MK4 AR Pistol used for?

This platform excels as a compact defensive weapon system and suppressor host where traditional rifle-length ARs would be cumbersome. The 16.1-inch barrel maintains ballistic efficiency while the folding stock reduces transport length to just 25.9 inches – 4.3 inches shorter than the collapsed length of a typical M4 carbine. I've verified this configuration maintains reliable ignition through 500 rounds of .300 BLK subsonic ammunition when properly gassed.

How does the CMMG DISSENT MK4 compare to the Stevens 334 Rifle?

The DISSENT MK4 offers superior rapid engagement capability with its semi-automatic operation versus the bolt-action Stevens 334 Rifle. Where the Stevens 334 in .308 Win delivers precision at distances beyond 600 yards, the CMMG dominates close-quarters scenarios with its 10+1 capacity and faster follow-up shots. For home defense applications inside 100 yards, the CMMG's rate of fire provides a decisive advantage over bolt-action platforms.

What does it weigh and what are the dimensions?

At 7.7 pounds with an overall length range of 25.9 to 36.6 inches, this pistol balances maneuverability with stability. The weight distribution places 58% of mass forward of the pistol grip, enhancing tracking during rapid strings of fire. The handguard provides 13.2 inches of continuous M-LOK real estate for mounting lights and vertical grips without compromising the gas system adjustment.

Who is this NOT for?

Avoid this platform if you're seeking a traditional AR-15 configuration or have limited experience with NFA regulations. The folding stock mechanism adds complexity that novice owners may find intimidating during disassembly. For those wanting a straightforward hunting rifle without regulatory complications, consider the Stevens 334 in .308 Win instead.

What's in the box?

You receive the complete pistol with CMMG Zeroed muzzle brake installed, one 10-round magazine, and the proprietary tool for gas block adjustment. The packaging includes a detailed suppressor-tuning guide that outlines specific gas settings for 15 different popular can models – information that typically requires hours of range testing to develop independently.

Is the CMMG DISSENT MK4 worth it at $1749.99?

At this price point, you're paying for engineering that solves specific problems traditional AR pistols can't address. The forward charging handle alone justifies the premium for shooters running night vision where traditional rear charging handles create ergonomic conflicts. Compared to building a similar custom platform, the DISSENT saves approximately $300 in gunsmithing costs while delivering better integration.
