The CMMG Dissent Mk4 5.7x28mm Pistol: Redefining Compact Personal Defense

Are you searching for a genuinely groundbreaking personal defense weapon (PDW) that defies conventional AR-platform limitations? Do you need a firearm that combines potent stopping power with unparalleled portability and discreet carry capabilities? Look no further than the CMMG DISSENT Mk4 5.7x28mm pistol, a revolutionary buffer-less AR15-style firearm designed to be the ultimate compact self-defense solution. This isn't just another AR pistol; it's a meticulously engineered system built for those who demand the smallest footprint without compromising on performance or reliability.

The CMMG DISSENT answers critical questions for firearm enthusiasts, tactical professionals, and responsible citizens: "What is the most compact AR-style firearm available for self-defense?" "How can I achieve AR-15 ergonomics and functionality in a truly stowable package?" and "Is the 5.7x28mm caliber suitable for a primary defense weapon?" The DISSENT addresses these challenges head-on, setting a new standard for portable firepower.

Unprecedented Portability: The Buffer-Less Revolution

The most defining feature of the CMMG DISSENT, and the innovation that truly sets it apart, is its patent-pending Compact Action. For decades, the AR-15 platform has been constrained by the necessity of a buffer tube extending from the rear of the receiver. This essential component, housing the recoil spring and buffer, dictates the overall length of the firearm and limits its ability to be truly compact or folded.

CMMG's engineers have completely re-imagined the AR operating system, integrating the entire action and recoil system within the upper receiver. This eliminates the need for a traditional buffer tube entirely, allowing for a significantly reduced overall length and enabling the use of a standard Picatinny buffer adapter at the rear. Imagine an AR-platform firearm that can be easily stored in a backpack, a discreet case, or even the glove compartment of a vehicle, ready for immediate deployment. This level of portability makes the CMMG DISSENT an ideal choice for:

• Home Defense: Maneuvering in tight indoor spaces.
• Vehicle Defense: Keeping a potent firearm readily accessible in a car or truck.
• Discreet Carry: Transporting a powerful weapon without drawing attention.
• Backpacking/Outdoor Expeditions: A lightweight, compact companion.
• Professional Use: For law enforcement or security personnel requiring a highly concealable yet effective primary weapon.

The Power of Precision: 5.7x28mm Caliber and Radial Delayed Blowback

Chambered in the high-velocity 5.7x28mm cartridge, the CMMG DISSENT combines a flatter trajectory with manageable recoil, making it an excellent choice for a Personal Defense Weapon. The 5.7x28mm round is renowned for its:

• High Velocity: Exceptional speed contributes to effective terminal ballistics.
• Low Recoil: Allows for rapid follow-up shots and enhanced control, especially important in a compact firearm.
• Lightweight Ammunition: Enables higher magazine capacities without excessive weight.
• Excellent Penetration Capabilities: Depending on the specific ammunition type, the 5.7x28mm can offer impressive penetration.

The DISSENT leverages CMMG's renowned Radial Delayed Blowback™ operating system. This innovative system, unique to CMMG, uses a bolt that rotates slightly to delay the blowback action, allowing chamber pressures to drop before the bolt fully unlocks. The benefits of this system are:

• Reduced Recoil: Works in conjunction with the 5.7x28mm caliber to further mitigate felt recoil.
• Enhanced Reliability: Provides smoother, more consistent cycling.
• Cleaner Operation: Less gas blowback compared to direct impingement systems.

This intelligent combination of the 5.7x28mm cartridge and Radial Delayed Blowback technology ensures that despite its compact size, the DISSENT delivers reliable, effective, and controllable performance when it matters most.

Design for Dynamic Use: Key Features and Ergonomics

Every aspect of the CMMG DISSENT Mk4 has been engineered with the end-user in mind, focusing on rapid deployment, intuitive handling, and long-term durability.

• 6.5-inch Free-Floated Barrel: This compact barrel length is optimized for the 5.7x28mm cartridge, balancing ballistic performance with the DISSENT's core mission of extreme portability. The free-floated design enhances accuracy by preventing contact with the handguard, minimizing external pressure on the barrel. The barrel is finished with Black Nitride for superior corrosion resistance and wear.
• 5.5-inch M-LOK® Handguard: The M-LOK system is a modern standard for accessory attachment, allowing users to easily mount lights, lasers, grips, and other tactical essentials directly to the handguard. This modularity ensures the DISSENT can be customized to suit individual preferences and mission requirements.
• Forward Non-Reciprocating Side Charger: A standout ergonomic feature, the DISSENT's side charging handle is ambidextrous and does not move during firing. This allows shooters to cycle the action without breaking their sight picture or re-positioning their grip on the firearm. It's an intuitive design choice that significantly improves user experience, especially in high-stress situations.
• 1913 Picatinny Rail Buffer Adapter: In place of a traditional buffer tube, the DISSENT features a robust 1913 Picatinny rail at the rear of the receiver. This universal interface allows for seamless attachment of various pistol braces or compatible stocks (NFA rules apply, see below), providing unparalleled customization for stability and shooting comfort.
• Coyote Tan Cerakote Finish: The DISSENT is available with a durable Coyote Tan Cerakote finish on the receiver. Cerakote is a ceramic-based coating known for its exceptional resistance to abrasion, corrosion, and chemical damage, ensuring your firearm maintains its aesthetic and protective qualities even in harsh environments.
• TriggerTech 2 Stage Trigger: A high-quality TriggerTech 2 Stage trigger is a standard feature. TriggerTech triggers are celebrated for their crisp break, minimal overtravel, and short reset, contributing significantly to improved accuracy and shooter confidence.
• Ambidextrous Safety: Catering to both left and right-handed shooters, the DISSENT features an ambidextrous safety selector, allowing for quick and intuitive manipulation regardless of the shooter's dominant hand.
• Optic Ready: The flat-top upper receiver is ready to accept your preferred optics, from red dot sights to low-power variable optics, allowing for precise aiming and rapid target acquisition.

Important Considerations: NFA Rules and State Compliance

As a responsible firearm owner, understanding the legal landscape is paramount. The CMMG DISSENT is shipped from the factory in a pistol configuration. It is crucial to be aware of the following:

• NFA Rules May Apply: Adding a stock to a pistol like the CMMG DISSENT will reclassify it as a Short-Barreled Rifle (SBR) under the National Firearms Act (NFA). SBRs are subject to specific federal regulations, including registration and tax stamp requirements. It is the owner's responsibility to comply with all federal, state, and local laws regarding firearm configuration. For comprehensive details, it is highly recommended to consult official NFA resources.
• State Magazine Capacity Restrictions: Firearms shipping to states with magazine capacity restrictions will only include 10-round magazines in place of standard capacity magazines. CMMG does not address any other state compliance requirements for further restricted states. Always verify your local and state firearm laws before purchasing.
