CMMG Dissent BR47 7.62×39 16.10 in Empire
About this product
The CMMG Dissent BR47 7.62×39 16.10 in Empire is a non-NFA firearm platform engineered for 7.62×39mm that uses an AK-pattern magazine system within an AR-format receiver, specifically built without muzzle threads to maintain compliance in restrictive jurisdictions. This design approach acknowledges the increasing number of state-level assault weapon bans that target threaded barrels as a prohibited feature. The 16.10-inch Empire profile barrel is crowned and recessed, not threaded, a deliberate choice that prioritizes legal operation over universal suppressor compatibility.
What is the CMMG Dissent BR47 used for?
The Dissent BR47 is designed as a legal, high-capacity-magazine-fed intermediate cartridge rifle for jurisdictions with threaded barrel bans, functioning as a compliant hunting and target platform. For Montana hunters, this means a semi-auto 7.62×39 setup for boar, coyote, or deer within 250 yards, directly usable in states like California or New York where a standard AR-15 in 7.62×39 would be classified as an 'assault weapon' due to its muzzle device. Its fixed-muzzle design and Magpul SGA stock create a durable, grab-and-go tool less susceptible to debris fouling than a threaded muzzle.
How does the CMMG Dissent BR47 compare to the Stevens 334 Rifle in .308 Win?
The CMMG Dissent BR47 provides rapid, semi-automatic follow-up shots with a 10+1 capacity, while the Stevens 334 in .308 Win offers superior long-range ballistic precision from a locked-breech bolt-action system. The bolt-action Stevens will typically group under 1 MOA with match ammunition, whereas the gas-operated Dissent is a 2-3 MOA platform designed for fast, minute-of-vitals accuracy on moving or multiple targets. For disciplined long-range shooting past 300 yards, the Stevens is objectively better; for defensive scenarios or fast-paced hunting in thick brush under 200 yards, the Dissent's action and magazine system are superior.
What does it weigh and what are the dimensions?
Unloaded, the rifle weighs 7.90 lbs (3.58 kg) and measures 37.80 inches (960 mm) in overall length with the stock extended. The 16.10-inch (409 mm) barrel contributes significant weight forward of the receiver, giving it a balance point roughly 5 inches ahead of the magazine well, which aids in managing the cartridge's recoil impulse. Its height from the bottom of the Magpul stock to the top of the Picatinny rail is approximately 8.25 inches, a critical measurement for optic and cheek weld compatibility.
Who is this NOT for?
This rifle is not for a shooter whose primary goal is attaching a muzzle brake, compensator, or suppressor, as the non-threaded, crowned Empire barrel is a permanent, non-negotiable feature. It is also a poor choice for someone seeking a lightweight backpacking rifle, as its 7.90-lb weight is over 2.5 lbs heavier than a Stevens 334 in .243 Win. Finally, purists who demand traditional AK manual of arms, including the rock-and-lock magazine insertion, will be frustrated by its AR-style lower receiver and magazine release.
What's in the box?
The rifle ships with two Magpul 10-round PMAGs for AK-pattern 7.62×39, a basic owner's manual, and a chamber flag. CMMG does not include tools, a case, or a optic in the standard package, which reflects its positioning as a component for knowledgeable builders or shooters. You should budget an additional $150-$300 for a quality hard case, a set of hex keys for rail attachment, and mounting hardware for any optic you plan to install on the full-length top rail.
Is the CMMG Dissent BR47 worth it at $2040.99?
At $2040.99, the Dissent BR47 is a justifiable expense for a shooter who legally requires a non-threaded, semi-automatic rifle that accepts readily available, high-capacity AK magazines, as it solves a specific regulatory problem with robust engineering. The cost reflects its ambidextrous controls, non-reciprocating side charger, and Zeroed single-stage trigger—features not found on a $600 PSA AK or a compliant AR-15 build using a pin-and-weld muzzle device. For a shooter without legal restrictions, a standard AR-15 in 5.56 NATO or a traditional AK platform offers more versatility and accessory options for several hundred dollars less.

Pros & cons
What works
- Solves the threaded-barrel ban problem—permanent 16.10" non-NFA compliant barrel
- Accepts ubiquitous AK-pattern magazines—10, 30, or 40-round capacity where legal
- Full ambidextrous controls—reversible safety, non-recip side charger, AK-style mag release
- Zeroed single-stage trigger—clean 4.5 lb break out of the box, no grit or creep
Trade-offs
- No muzzle device compatibility—permanent crowned barrel eliminates suppressor or brake options
- Heavy for its class—7.90 lbs unloaded is 1.2 lbs heavier than a comparable BRN-180 upper on a standard lower
- Proprietary trigger system—limits aftermarket upgrades to CMMG-specific units only
- Premium price for a compliance feature—$500+ over a standard threaded-barrel 7.62×39 AR upper

Frequently asked questions
- Is it compatible with standard AK-47 magazines?
- Yes, the lower receiver is machined to accept standard AK-pattern 7.62x39mm magazines, including Magpul PMAGs, US Palm, and surplus steel magazines. The included Magpul 10-round magazines are designed for compliance in capacity-restricted states, but the rifle will function with 30-round or 40-round magazines where legally permitted. The magazine well is slightly wider than a standard AR-15 magwell to accommodate the AK magazine's rock-and-lock geometry.
- Does the non-threaded muzzle accept any muzzle devices?
- No, the Empire profile barrel is crowned and recessed with precisely zero threads—it is a permanent, non-threaded design. You cannot attach a muzzle brake, flash hider, or suppressor without permanent, irreversible gunsmithing that would involve cutting, threading, and potentially re-profiling the barrel, which would void the warranty and likely violate the rifle's designed compliance status. This is a core, non-negotiable feature of the platform.
- How long does shipping and delivery take for this item?
- As an 'Online Only' item, shipping typically takes 3-5 business days for processing and verification, followed by 2-7 business days for transit via FedEx or UPS, depending on your location relative to our warehouse. The total timeline from order to delivery at your chosen Federal Firearms License (FFL) holder is generally 7-12 business days. You will receive tracking information via email once the shipment label is created.
- Can I return it if I don't like how it handles?
- Returns are accepted within 30 days of the original shipment date only if the firearm is unfired, in its original packaging with all accessories, and accompanied by the original sales documentation. A 15% restocking fee applies to all non-defective returns, and the customer is responsible for the cost of shipping the firearm back to us via a licensed carrier and for any transfer fees charged by their FFL to receive the return. We strongly recommend handling a similar platform at a local dealer before purchasing.
- Does this work with a standard AR-15 trigger group?
- No, it uses CMMG's proprietary Zeroed single-stage trigger unit which is a drop-in cassette system, not compatible with standard mil-spec AR-15 fire control groups. The trigger pack is designed around the Dissent's specific hammer geometry and safety cross-bolt configuration. Replacement or upgrade must be done with CMMG-specific components or aftermarket triggers specifically listed as compatible with the CMMG Dissent series.
