CMMG Dissent BR4 9mm Carbine 16.1" Barrel 10rd Magazine Black

The CMMG Dissent BR4 represents a significant advancement in pistol-caliber carbine design, combining radial delayed blowback operation with precision manufacturing. This 9mm carbine delivers exceptional accuracy and reliability while maintaining the familiar AR-15 ergonomics shooters expect.

What Makes This Different

Unlike traditional straight blowback systems, the Dissent BR4 utilizes CMMG's patented radial delayed blowback technology, reducing felt recoil by up to 30% compared to conventional 9mm carbines. The system operates with lighter bolt weights while maintaining positive extraction and ejection. This translates to faster follow-up shots and improved accuracy during rapid fire sequences.

Key Features

• Radial delayed blowback system reduces recoil and improves controllability
• 16.1-inch barrel with black nitride finish for corrosion resistance and extended service life
• 7075-T6 aluminum receiver construction provides strength-to-weight optimization
• 13.5-inch proprietary M-LOK handguard offers extensive accessory mounting options
• Magpul SGA stock delivers adjustable length of pull and cheek weld
• 10-round magazine capacity complies with restricted state regulations
• Standard AR-15 trigger group compatibility allows for easy upgrades

The Dissent BR4 excels in competitive shooting environments where rapid target transitions are critical. Law enforcement agencies appreciate the reduced overpenetration risk of 9mm ammunition combined with carbine-length sight radius accuracy. The platform handles both subsonic and supersonic ammunition reliably, making it suitable for suppressed applications. Weather sealing at critical junctions ensures function in adverse conditions.
