Exploring the CMMG DISSENT BR4: A Modern Sporting Rifle for Restrictive States

If you live in a place where a standard AR-15 is not legal, something like the CMMG DISSENT BR4 seems like the answer to a prayer – a reliable, legal, semi-automatic, ranch-style carbine engineered for modern functionality while staying compliant in restrictive states. If pressed prior to the CMMG DISSENT’s launch, we’d have settled on the FightLite SCR or a Beretta 1301 if we needed something semi-auto that we would reach for if life or home depended on it. We now put the DISSENT at the top of the list, when paired with quality ammo.

The BR4 DISSENT breaks from traditional AR designs by incorporating a Magpul Remington 870 SGA shoulder stock and a left-hand, side-mounted charging handle, eliminating the need for a buffer tube and pistol grip. This innovation allows the BR4 to retain popular AR-15 magazine compatibility, M-Lok customization, and easy optics mounting, all within a sleek, legal design that meets the needs of today’s firearm enthusiasts.

The CMMG DISSENT BR4 is a remarkable addition to the world of modern sporting rifles, particularly for those residing in states with stringent firearm regulations. Drawing inspiration from firearms like the FightLite SCR, Foxtrot Mike Ranch Rifle, and SIG MCX Regulator, the CMMG DISSENT BR4 combines traditional elements with contemporary innovations to create a rifle that’s both versatile and compliant with the laws of 47 states.

Why Choose a CMMG DISSENT BR4?

In a state like California for example, if we are choosing an AR style rifle for hard-use, where we might have to bet our life on it, we have a very hard time accepting the fact that its magazine is locked in place. Its a horrible trade off versus not having to look at an ugly featureless rifle. The bottom line is that if there is a malfunction where time is of the essence, dropping the mag and clearing the malfunction just isn’t feasible. It’s impossible. You’re stuck with a dead gun, and you’ll need to have a backup option handy.

On the other hand, imagine you have a CMMG DISSENT. You’ve got a handy, lightweight rifle that works, is lightweight, maneuverable, accepts a red dot, and is chambered in 5.56, or 300 blackout, complete with proper, removable AR magazines. In a state where compromises are necessary, this really does seem like the way to go. Otherwise, there’s an argument to be made for skipping the AR altogether and opting for something like a Beretta 1301.

CMMG DISSENT BR4 – A Closer Look

One of the standout features of the CMMG DISSENT BR4 is its configuration designed to meet legal requirements in states with restrictions on certain firearm features. The rifle is equipped with a fixed stock, eschews a vertical pistol grip, and forgoes a bayonet lug. Additionally, it utilizes a muzzle brake instead of a flash hider, further contributing to its compliance with state laws. However, it’s important to note that despite these modifications, the CMMG DISSENT BR4 remains illegal in New York, Illinois, and Washington, meaning residents of these states will need to seek alternatives.

The heart of the CMMG DISSENT BR4 lies in its innovative lower receiver, which is not only compatible with standard AR magazines but also accepts readily available Remington 870 stocks. This model comes standard with a Magpul SGA 870 stock, offering a familiar and reliable foundation for users. The lower receiver also features several deviations from the traditional AR platform, including a more streamlined design, a shorter magazine well, and a reversible cross-bolt safety that mirrors the functionality of a Remington 870. This safety selector, along with an oversized bolt catch and ambidextrous magazine catch, enhances the rifle’s usability for both left and right-handed shooters.

Moving to the upper receiver, the CMMG DISSENT BR4 maintains a sleek and practical design. It is a slick-side upper, which means it lacks a forward assist but compensates with a brass deflector block. The rifle also includes a reversible, non-reciprocating charging handle, providing flexibility and convenience in operation. Complementing these features is a full-length M-LOK handguard, which offers ample space for attaching accessories and customizing the rifle to your specific needs.

Customization Options Abound

The CMMG DISSENT BR4’s impressive versatility extends to its caliber options as well. Available in seven different calibers—5.56mm, 300 BLK, 9mm, 22 ARC, 6mm ARC, 6.5 Grendel, and 350 Legend—the rifle caters to a wide range of shooting preferences, from target shooting to hunting. Whether you’re looking for a standard option like the 5.56mm or something more specialized like the 6.5 Grendel, the CMMG DISSENT BR4 has you covered. This variety allows users to choose the caliber that best suits their needs while maintaining the same reliable platform. In a home defense role, we’d opt for 5.56 or 300 Blackout. Frankly, we’d get ours in 5.56 and buy a ton of IMI RazorCore 77 grain, and call it a day.

Adding to its appeal is the selection of Cerakote finishes available for the CMMG DISSENT BR4. With seven color options—Armor Black, Sniper Grey, Charcoal Green, Coyote Tan, Midnight Bronze, Titanium, and Tungsten—you can not only optimize your rifle for performance but also personalize its appearance to match your style.

At its core, the CMMG DISSENT BR4 is built on quality components, including aircraft-grade aluminum receivers and CMMG’s patented Compact Action, which allows for a more compact and portable rifle. The non-reciprocating side charger and full-length M-LOK handguard are standard, along with the Cerakote finish, which ensures durability and protection against the elements. The rifle is also equipped with CMMG’s ZEROED Drop-In Trigger, offering a crisp 4.5-pound pull weight that enhances accuracy and control.

Moreover, the CMMG DISSENT BR4’s adjustable gas block is a notable feature for those looking to fine-tune their shooting experience. Whether you’re shooting suppressed or simply want to optimize the rifle for your preferred ammunition, the adjustable gas block provides the flexibility to dial in the perfect settings. This will be especially helpful if you decide to suppress it.

In addition to its technical prowess, the CMMG DISSENT BR4 is designed with practical use in mind. The rifle ships with two 10-round Magpul PMags, making it ready for use out of the box. For those in states with stricter magazine capacity laws, CMMG offers 5-round magazines to ensure compliance.

Conclusion

As we stated in the beginning, we think this rifle is the answer to a lot of prayers and is a much better option than what was available previously. The CMMG DISSENT BR4 is a rifle that expertly balances modern features with legal compliance, making it an ideal choice for firearm enthusiasts in restrictive states. Its thoughtful design, caliber versatility, and quality construction make it a worthy investment for anyone looking to add a reliable and adaptable firearm to their collection. Whether you’re interested in its legal compliance, its range of customization options, or simply its overall performance, the CMMG DISSENT BR4 is a rifle that’s definitely worth your consideration and further research.
