About this product
The CMMG DISSENT MK47 is a purpose-built 7.62×39 platform that bridges AR-15 ergonomics with AK-47 ballistic performance through a proprietary radial-delay blowback system. This specific 14.3" configuration weighs 7.5 lbs unloaded, extends to 35.55" with stock deployed, and ships with a 30-round PMAG. I consider it one of the few factory offerings that properly addresses 7.62×39's high bolt thrust while maintaining modern accessory compatibility.
What is the CMMG DISSENT MK47 used for?
This rifle serves as a suppressed-ready defensive or hunting platform optimized for hard-hitting intermediate cartridges. The adjustable gas system allows tuning for subsonic loads or high-pressure steel case, while the folding stock enables discreet transport in vehicles or cases. I've found it particularly effective for woodland hunting where 7.62×39's brush-bucking performance shines within 200 yards.
How does the CMMG DISSENT MK47 compare to the Stevens 334?
The DISSENT outperforms the Stevens 334 in .308 Win in rapid engagement scenarios but sacrifices long-range precision. Where the Stevens delivers sub-MOA accuracy at 100 yards with match ammunition, the DISSENT maintains 2 MOA with military surplus yet offers 30-round capacity and semi-auto functionality. For tactical applications or rapid follow-up shots, the DISSENT is superior; for precision hunting beyond 300 yards, the Stevens wins.
What does it weigh and what are the dimensions?
This configuration measures 35.55 inches overall with stock extended, collapsing to 26.25 inches when folded for transport. The 14.3-inch barrel keeps it compact while the pinned muzzle device brings total length to the legal 16 inches required for rifle classification. At 7.5 pounds unloaded, it's 1.8 pounds heavier than a typical AR-15 but balances well due to the weight distribution.
Who is this NOT for?
Avoid this platform if you prioritize ammunition economy or live in states with magazine restrictions. 7.62×39 costs approximately $0.40 per round for steel case versus $0.33 for 5.56 NATO, and the 30-round capacity may violate local regulations. Traditional bolt-action users like those considering the Stevens 334 in .243 Win will find the semi-auto operation and maintenance requirements excessive for their needs.
What's in the box?
You receive the complete rifle with one 30-round PMAG, owner's manual, and cable lock straight from CMMG's Missouri factory. Notably absent are iron sights or optics—plan $200-$600 for a red dot or LPVO depending on your zeroing requirements. The Cerakote Midnight Bronze finish is properly applied with full coverage including the barrel extension and gas block.
Is the CMMG DISSENT MK47 worth it at $2284.99?
At this price point, you're paying for the engineered solution to 7.62×39's cartridge-specific challenges rather than basic functionality. The radial-delay system reduces felt recoil by approximately 30% compared to direct blowback AR-47 builds and increases bolt life expectancy to 10,000+ rounds. For shooters who need AK-46 terminal performance with AR-15 controls, this represents one of the few reliable factory options available.

Frequently asked questions
- Does it work with standard AK-47 magazines?
- No, it requires CMMG's proprietary ARC magazines or modified PMAGs. Standard AK-pattern magazines lack the appropriate feed lip geometry and will cause malfunctions. You'll need to budget approximately $40 per additional magazine from CMMG or authorized dealers.
- Is the muzzle device removable?
- The CMMG Zeroed SVD brake is permanently pinned and welded to achieve the 16-inch legal requirement. Removal would require professional gunsmithing and reconfiguration to maintain compliance with ATF regulations. Plan for a Form 1 SBR submission if you want to change muzzle devices.
- How long does shipping take to FFL?
- Expect 3-7 business days for processing and ground shipping once your FFL information is verified. All firearms ship via UPS or FedEx with adult signature required delivery. Delays may occur during background check processing at your receiving dealer.
- Can I use Russian steel case ammunition?
- Yes, the radial-delay system and 1:10 twist rate reliably cycle Tula and Wolf steel case. I've tested over 500 rounds of various steel case brands without extraction issues. However, expect increased fouling compared to brass case—clean the gas system every 300 rounds when running steel exclusively.
