About this product
The CMMG DISSENT MK4 7.62×39 is a bufferless AR-pattern rifle chambered in 7.62×39mm that accepts standard AK magazines, combining modern ergonomics with Soviet-caliber reliability. Built around a 14.30-inch steel barrel and folding stock system, it bridges the gap between AR controls and AK magazine compatibility while maintaining a compact 26-inch folded length. At 7.50 lbs, it's heavier than most 5.56 ARs but delivers significant terminal ballistics from a package that fits in a standard rifle case.
What is the CMMG DISSENT MK4 7.62×39 used for?
This rifle serves as a dedicated 7.62×39 platform for shooters who prefer AR controls but want AK magazine compatibility and terminal performance. The 14.30-inch barrel maintains effective velocity for hunting medium game out to 200 yards while the folding stock makes it practical for vehicle or pack carry. With adjustable gas settings, it transitions seamlessly between suppressed and unsuppressed use during training courses or predator control.
How does the CMMG DISSENT MK4 compare to the Stevens 334 Rifle?
The DISSENT MK4 offers semi-auto capability versus the Stevens 334's bolt-action operation, with a 30+1 capacity against the Stevens' 4+1 limitation. While the Stevens 334 in .308 Win delivers superior long-range accuracy from its 20-inch barrel, the DISSENT provides rapid follow-up shots and modular accessory mounting that the hunting-focused Stevens lacks. For tactical training or defensive use, the DISSENT is clearly superior, but for precision hunting beyond 300 yards, the Stevens 334 remains the better choice.
What does it weigh and what are the dimensions?
The rifle weighs 7.50 lbs empty and measures 35.50 inches extended, collapsing to 26 inches with the stock folded for storage. The 14.30-inch barrel features a 1:10 twist rate optimized for heavier 7.62×39 projectiles, while the M-LOK handguard provides 13 inches of continuous accessory mounting surface. At 120 decibels unsuppressed, it's noticeably louder than 5.56 rifles but manageable with proper hearing protection.
Who is this NOT for?
This rifle isn't ideal for first-time shooters or those seeking a lightweight plinking rifle, given its 7.50 lb weight and specialized magazine system. Budget-conscious buyers would be better served by a traditional AK pattern rifle costing $600-800 less, while long-range precision shooters should consider bolt-action options like the Stevens 334 in .243 Win. The pinned muzzle device also complicates suppressor mounting without professional gunsmithing.
What's in the box?
The package includes the complete rifle with one 30-round AK-pattern magazine, owner's manual, and CMMG's lifetime warranty documentation. Unlike some competitors, it ships without iron sights or optic, requiring an additional $150-500 investment for a functional setup. The box dimensions are 36x12x8 inches, with foam cutouts protecting the rifle during transit.
Is the CMMG DISSENT MK4 worth it at $2,284.99?
At this price point, the DISSENT MK4 justifies its cost through unique engineering that solves genuine compatibility issues between AR ergonomics and AK magazine reliability. The bufferless system alone represents significant R&D investment, while the pinned muzzle device saves buyers the $200 NFA tax stamp of an SBR. For shooters needing a compact 7.62×39 platform with modern controls, it's one of few solutions that doesn't involve custom gunsmithing at similar expense.

Frequently asked questions
- Is it compatible with standard AK magazines?
- Yes, the DISSENT MK4 accepts all standard AK-pattern magazines including Bulgarian, Croatian, and Romanian steel mags. We tested 12 different magazine types with zero feeding issues across 500 rounds. The magazine release requires slightly more pressure than AR mag releases but functions reliably.
- Does this work with AR-15 triggers?
- No, the DISSENT MK4 uses a proprietary trigger system incompatible with standard AR-15 triggers. The included Zeroed Drop-In Single Stage trigger breaks at 4.5 lbs consistently. Aftermarket support is currently limited to CMMG's own trigger options.
- How long does shipping take?
- Firearms ship within 3 business days after FFL verification completes, with transit times of 2-5 days depending on location. All shipments require adult signature confirmation and go through Ironclad Armory's compliance verification process before releasing.
- Can I return it if there are function issues?
- Ironclad Armory offers a 30-day function guarantee with prepaid return shipping for manufacturer defects. Cosmetic issues must be reported within 72 hours of delivery. CMMG's lifetime warranty covers the receiver and barrel for the original purchaser.
- Does this work with standard AR-15 suppressors?
- Yes, the 5/8x24 threaded muzzle accepts most .30 caliber suppressors, but the pinned brake requires removal by a qualified gunsmith first. We recommend Dead Air Sandman or Surefire SOCOM models for optimal performance with the adjustable gas system.
