Are you searching for the ultimate compact firearm that redefines portability without compromising on performance or reliability? Do you need a personal defense weapon that’s incredibly easy to maneuver in tight spaces, simple to transport, and ready for immediate action? The CMMG DISSENT in 5.7x28mm is engineered precisely for these challenges, pushing the boundaries of what’s possible in an AR-style pistol platform. Designed for the discerning individual who demands both innovation and uncompromising quality, the CMMG DISSENT, specifically the Mk4 model with its 6.50-inch barrel and striking Midnight Bronze Cerakote receiver, represents a new era in personal defense weaponry.

Unveiling the Buffer-less Revolution: CMMG's Compact Action

At the heart of the CMMG DISSENT's groundbreaking design is its revolutionary buffer-less system, leveraging CMMG's patent-pending Compact Action. For years, the Achilles' heel of AR-15 platform pistols and short-barreled rifles (SBRs) has been the mandatory buffer tube, an extension that significantly adds to the weapon's overall length and often dictates how it can be stored or deployed. The DISSENT elegantly solves this by completely integrating the action and recoil system within the upper receiver itself. This innovative engineering means the DISSENT can operate flawlessly without any protruding buffer tube, leading to an incredibly short and stowable firearm.

Imagine a powerful AR-style platform that fits effortlessly into a backpack, a discreet case, or a vehicle console – the DISSENT transforms this vision into reality. This design choice is not just about compactness; it directly contributes to enhanced mobility, quicker deployment, and superior concealment capabilities, making it an ideal choice for personal protection or professional applications where discretion is paramount. With an overall length (OAL) of just 14.70 inches, the CMMG DISSENT stands as one of the shortest and most stowable Personal Defense Weapons CMMG has ever built, setting a new benchmark for compact AR-style firearms.

The Power and Precision of 5.7x28mm

Caliber choice is paramount for a personal defense weapon, and the CMMG DISSENT's chambering in 5.7x28mm is a deliberate and highly effective decision. This high-velocity, low-recoil cartridge, originally developed for NATO personal defense weapons, offers a compelling balance of attributes. What makes the 5.7x28mm so suitable for a compact platform like the DISSENT?

• High Velocity: Despite its small projectile, the 5.7x28mm round achieves impressive velocities, contributing to flat trajectories and excellent terminal performance against various targets. This characteristic helps in maximizing effectiveness within a compact barrel length.
• Low Recoil: One of its most significant advantages is its exceptionally mild recoil impulse. This allows for faster, more accurate follow-up shots and a more comfortable shooting experience, particularly crucial in a lightweight, compact firearm. Shooters of all experience levels will appreciate how manageable this cartridge is, making extended range sessions enjoyable and improving training efficiency.
• Capacity: The DISSENT in 5.7x28mm typically ships with a 32-round magazine, offering substantial capacity for self-defense scenarios or competitive shooting. This high capacity means fewer reloads and sustained firepower when it matters most.
• Effectiveness: While often compared to traditional pistol calibers, the 5.7x28mm often outperforms them in certain metrics due to its high velocity and specialized bullet designs, making it a formidable and reliable personal defense round.

Engineered for Performance: Radial Delayed Blowback™ Operating System

Beyond its buffer-less design, the CMMG DISSENT further distinguishes itself with CMMG’s renowned Radial Delayed Blowback™ operating system. Unlike traditional direct impingement or standard blowback systems often found in AR platforms, Radial Delayed Blowback utilizes a unique bolt design that precisely delays the bolt’s rearward movement during the initial phase of firing. This delay is achieved by manipulating the rotational forces of the bolt. As the round is fired, gas pressure begins to push the bolt rearward. However, the bolt head is designed with locking lugs that are radially delayed, meaning they must rotate and unlock from the barrel extension before the bolt can fully retract. This clever mechanism allows chamber pressures to drop to safer, more manageable levels before extraction occurs, resulting in a number of critical advantages:

• Smoother Operation: The delayed action significantly reduces the felt recoil and muzzle rise, contributing to the DISSENT's remarkably smooth shooting experience, which is particularly noticeable in a compact firearm.
• Enhanced Reliability: By allowing pressures to normalize, the system mitigates common issues like premature extraction or violent cycling, leading to superior reliability across various ammunition types and environmental conditions.
• Reduced Wear and Tear: The gentler cycling action also lessens wear on internal components, contributing to the firearm's longevity and consistent performance over thousands of rounds, ensuring your investment lasts.

This combination of the Compact Action and Radial Delayed Blowback technology is what elevates the DISSENT beyond a mere compact AR pistol; it makes it a precision-engineered, high-performance Personal Defense Weapon that stands out in its class.

Thoughtful Ergonomics and User Experience

The CMMG DISSENT is not just about innovative internal mechanisms; it's also meticulously designed for the user. Every feature contributes to a seamless and intuitive shooting experience, whether you're a seasoned professional or a first-time firearm owner, ensuring that functionality matches its cutting-edge design.

• Forward Non-Reciprocating Side Charger: A standout ergonomic feature is the forward non-reciprocating side charger. Unlike traditional rear charging handles on AR-style platforms, this charging handle is positioned conveniently forward, allowing for quick and efficient manipulation without breaking your sight picture or moving the firearm from your shoulder (if a stock is attached, NFA rules apply). Crucially, it's non-reciprocating, meaning it doesn't move with the bolt carrier group during firing, enhancing safety and preventing interference. Its ambidextrous design means it can be easily switched from the left to the right side, accommodating both left and right-handed shooters with equal ease.
• M-LOK Handguard: The DISSENT features a 5.5-inch M-LOK free-float handguard.
