CMMG DISSENT 5.7x28mm Pistol: Redefining Compact Personal Defense Weapons

For individuals seeking the pinnacle of compact firearm design, the CMMG DISSENT Mk4 5.7x28mm Pistol stands out as a groundbreaking solution. Whether you prioritize discreet carry, maneuverability in close quarters, or an exceptionally portable defensive firearm, this innovative AR-style pistol is engineered to meet and exceed those demands. It’s an ideal choice for the discerning enthusiast, home defense specialist, or anyone requiring a highly capable firearm with an unparalleled small footprint.

What challenges does the CMMG DISSENT solve for modern firearm owners?
Traditional AR-15 platforms, while highly effective, are often hindered by the necessity of a buffer tube, which adds considerable length and limits true compactness. This becomes a significant concern for scenarios requiring a short, easily stowed weapon, such as vehicle defense, discreet transport in a backpack, or navigating tight spaces within a home. The CMMG DISSENT directly addresses this by completely eliminating the buffer tube, offering a true "Personal Defense Weapon" (PDW) experience without compromise.

Why the CMMG DISSENT is the Ultimate Compact Firearm

The CMMG DISSENT 5.7x28mm pistol, specifically the model identified by UPC 810097507968, redefines what’s possible in an AR-style platform. Its design innovations make it an excellent choice for a variety of applications:

• Unrivaled Portability: At just 14.70 inches overall length (OAL) and sporting a 6.50-inch barrel, the DISSENT is CMMG’s shortest and most stowable AR-style firearm to date. This makes it perfect for discreet carry, stowing in a backpack, or keeping readily accessible in a vehicle.
• Maneuverability in Confined Spaces: The ultra-compact design allows for superior handling and movement in close-quarter environments, making it an exceptional choice for home defense or tactical operations where space is limited.
• Discreet Profile: Its small size allows for easier concealment and transport, providing a low-profile solution without sacrificing defensive capability.
• Cutting-Edge Innovation: The DISSENT incorporates CMMG’s patent-pending Compact Action, a revolutionary design that contains the entire recoil system within the upper receiver, eliminating the need for a traditional buffer tube extending from the rear of the firearm. This is a game-changer for AR pistol design.
• Potent 5.7x28mm Caliber: Chambered in 5.7x28mm, known for its high velocity, flat trajectory, and low recoil, this pistol delivers remarkable performance in a compact package. The 32+1 capacity ensures ample firepower.

Engineering Excellence: Key Features That Set the DISSENT Apart

CMMG has meticulously engineered the DISSENT to deliver superior performance and reliability. Every aspect, from the operating system to the ergonomics, is optimized for the user.

The Revolutionary Compact Action System

At the heart of the DISSENT’s innovation is the patent-pending Compact Action. This proprietary system allows the entire action and recoil spring assembly to be self-contained within the upper receiver, freeing the lower receiver from the need for a buffer tube. This is what enables the DISSENT to achieve its remarkable brevity and makes it an ideal platform for a variety of brace or stock (NFA rules apply) configurations via its integrated 1913 Picatinny buffer adapter.

Renowned Radial Delayed Blowback™ Operating System

Working in harmony with the Compact Action is CMMG’s acclaimed Radial Delayed Blowback™ operating system. This system significantly reduces felt recoil by redirecting a portion of the gas rearward to delay the bolt’s unlocking, resulting in a smoother, more controllable shooting experience. This innovation contributes to faster follow-up shots and enhanced accuracy, especially beneficial in a compact firearm.

Ergonomics and User-Friendly Design

• Forward Non-Reciprocating Side Charger: The DISSENT features an intuitive non-reciprocating side charger, which can be easily swapped from left to right for ambidextrous operation. This design allows shooters to charge the weapon without breaking their sight picture or shifting their grip, maintaining focus on the target.
• Ambidextrous Safety: Catering to both left and right-handed shooters, the ambidextrous safety selector ensures ease of operation and enhanced user safety for all.
• M-LOK Free-Float Handguard: The 5.5-inch M-LOK handguard provides ample space for attaching accessories such as lights, lasers, and vertical grips, allowing for extensive customization to suit individual preferences and mission requirements. Its free-float design ensures maximum accuracy by preventing barrel deflection.
• OEM Grip and TriggerTech 2 Stage Trigger: Equipped with a comfortable OEM polymer grip and a high-performance TriggerTech 2 Stage trigger, the DISSENT offers an excellent out-of-the-box shooting experience, promoting precision and control.

Robust Construction and Premium Finishes

The CMMG DISSENT is built to last with high-quality materials and durable finishes.

• Receiver Material: The receivers are crafted from robust 7075-T6 Aluminum, known for its exceptional strength-to-weight ratio, ensuring durability without adding unnecessary bulk.
• Tungsten Gray Cerakote Finish: This specific model boasts a durable Tungsten Gray Cerakote finish on the receiver. Cerakote is renowned for its resistance to corrosion, abrasion, and chemicals, ensuring the firearm maintains its aesthetic appeal and protective qualities even in harsh environments.
• Black Nitride Barrel Finish: The 6.50-inch barrel features a black nitride finish, which enhances corrosion resistance and reduces friction for improved barrel life and consistent performance.
• Muzzle Device: Fitted with a compensator, the DISSENT further manages recoil and muzzle rise, contributing to a more comfortable and accurate shooting experience. The 1/2"x28 thread pattern also allows for easy attachment of other muzzle devices or suppressors.

The Power of 5.7x28mm: A Caliber Perfect for PDWs

The choice of the 5.7x28mm caliber for the CMMG DISSENT is a deliberate one, aligning perfectly with its role as a personal defense weapon. What makes the 5.7x28mm so effective in this platform?

• High Velocity, Low Recoil: The 5.7x28mm round is characterized by its small diameter, light bullet, and extremely high velocity. This translates to a very flat trajectory and surprisingly low recoil, making the DISSENT incredibly easy to shoot accurately and rapidly, even for novice users.
• Exceptional Ballistic Performance: Despite its small size, the 5.7x28mm round can deliver impressive terminal ballistics, especially when paired with modern ammunition designs, making it a formidable defensive cartridge.
• High Magazine Capacity: Standard magazines for the 5.7x28mm typically offer generous capacity, with this DISSENT model shipping with a 32+1 round magazine. (Note: Firearms shipping to states with magazine capacity restrictions will only ship with 10-round magazines in place of standard capacity magazines.)

CMMG's Commitment to Quality and Compliance

CMMG stands behind every product with a Lifetime Quality Guarantee, covering material and workmanship defects. This commitment to excellence provides peace of mind and ensures that your investment in a CMMG DISSENT is protected for the long term.

Understanding NFA Rules

It is crucial for potential owners to understand the legal implications of owning and modifying an AR pistol.

• The CMMG DISSENT is shipped in a pistol configuration, as identified by its classification and the absence of a traditional stock.
• NFA Rules May Apply: Adding a stock to this pistol will reclassify it as a Short Barreled Rifle (SBR) under the National Firearms Act (NFA), which requires specific registration with the ATF and compliance with federal regulations.
• State-Specific Compliance: While CMMG ensures compliance with magazine capacity restrictions where applicable (shipping with 10-round magazines to restricted states), purchasers are solely responsible for ensuring the firearm meets all other state and local regulations for further restricted states. It is highly recommended to consult local laws before purchasing.

Real-World Applications for Your CMMG DISSENT

The CMMG DISSENT 5.7x28mm pistol isn't just a range toy; it's a versatile tool designed for serious applications.

• Home Defense: Its compact size allows for easy maneuverability in hallways and rooms, while the 5.7x28mm caliber offers effective defensive capabilities with reduced over-penetration risk compared to some rifle calibers.
• Vehicle Defense: Easily stowed under a seat, in a console, or in a trunk, the DISSENT provides a readily accessible and potent defense option for those on the go.
• Outdoor Adventures/Camping: For those who carry a firearm for personal protection during outdoor activities, the DISSENT's light weight and small form factor make it an excellent companion.
• Backpack Gun: When discreet carry is paramount, the DISSENT can be comfortably and inconspicuously carried in many standard backpacks, offering a formidable defense solution when a full-sized rifle is impractical.
