The CMMG Inc. Dissent Mk4 – 22Arc – Sniper Gray 6061-T6 Aluminum Made a Bold First Impression
The CMMG Inc. Dissent Mk4 – 22Arc – Sniper Gray 6061-T6 Aluminum is a unique offering in the AR-15 world. Chambered in the novel 22 ARC (Advanced Rimfire Cartridge), this rifle aims to bridge the gap between the ubiquitous .22LR and larger centerfire cartridges. Its distinct feature is the compact design achieved by eliminating the traditional buffer tube, making it incredibly appealing for those prioritizing portability and discretion.
As someone deeply entrenched in the tactical gear world, I’m always searching for innovative solutions that enhance performance and adaptability. My main goal was to find a platform that offers AR ergonomics and handling but with a more manageable and affordable cartridge for training and small game hunting.
Upon unboxing the CMMG Dissent Mk4, the Sniper Gray finish on the 6061-T6 aluminum immediately caught my eye. The rifle felt solid and well-balanced despite its shorter overall length. The absence of a buffer tube was striking, contributing to a significantly reduced footprint.
Compared to traditional AR-15 pistols with buffer tubes, the CMMG Dissent offers a more streamlined and compact package. Options like the Sig Sauer MCX Rattler in .223 offer a similar compact form factor, but at a much higher price point and with significantly more recoil. The CMMG presented a compelling alternative focused on the .22 ARC cartridge and its associated benefits. I chose it for its innovative design, potential for suppressed shooting, and the promise of cost-effective training. My first impression was one of excitement; I was eager to see how this unique rifle performed in real-world scenarios.
