The CMMG 28B940CTI Dissent 22 ARC 16.10″ 6061-T6 Aluminum – Titanium Made a Bold First Impression
The CMMG 28B940CTI Dissent 22 ARC 16.10″ 6061-T6 Aluminum – Titanium arrives promising a compact, versatile, and highly accurate .22 ARC platform. Coming from CMMG, a name synonymous with innovative AR-platform firearms, expectations were understandably high. This particular model, with its 16.10″ barrel and distinct titanium finish, immediately caught my eye with its promise of blending portability with performance.
For years, I’ve grappled with finding a dedicated .22LR platform that could realistically mimic the ergonomics and feel of my primary AR-15 rifles. The goal was simple: affordable training that translated directly to proficiency with my centerfire rifles. Many rimfire options felt like toys; they lacked the weight, trigger feel, and overall handling characteristics necessary for effective cross-training.
Unboxing the CMMG Dissent, the first thing I noticed was the reassuring weight; it felt substantial, not cheap. The 6061-T6 aluminum receiver and titanium finish exuded quality, while the compact design hinted at its maneuverability. Compared to my dedicated .22LR AR upper from another manufacturer, the Dissent felt significantly more refined and purpose-built. This was not just another rimfire; it felt like a serious training tool.
My initial impression was definitely excitement; CMMG seemed to have delivered a product that addressed my specific needs and exceeded expectations in terms of build quality and aesthetics. I was eager to put it through its paces and see if its performance matched its promise.
Real-World Testing: Putting CMMG 28B940CTI Dissent 22 ARC 16.10″ 6061-T6 Aluminum – Titanium to the Test
First Use Experience
The CMMG Dissent made its debut at my local outdoor shooting range, a familiar environment where I could thoroughly evaluate its performance. I subjected it to a variety of .22LR ammunition, from standard velocity target loads to high-velocity rounds, to gauge its reliability. The weather was mild, with a slight breeze, ideal conditions for accuracy testing.
The Dissent proved exceptionally easy to use straight out of the box, requiring minimal adjustment. The controls were intuitive and familiar, closely mimicking those of a standard AR-15. After only a few magazines, the ergonomics became second nature. The initial shooting session revealed a few minor hiccups with some bulk-pack ammunition, but switching to higher-quality rounds solved those issues immediately.
Extended Use & Reliability
After several months of consistent use, the CMMG Dissent has proven to be a remarkably reliable and durable platform. It has endured hundreds of rounds without any significant issues. Regular cleaning and lubrication are essential, but the process is straightforward, similar to maintaining any AR-pattern firearm.
There are minimal signs of wear and tear, despite frequent use. The titanium finish remains scratch-free, and the aluminum receiver shows no signs of fatigue. Compared to my previous .22LR training upper, the Dissent has been a revelation; it’s far more reliable, accurate, and durable, making it a truly worthwhile investment.
