First Impressions of CMMG 28B260CTNG RESOLUTE MK4 22ARC 16.1 TUNG
The CMMG 28B260CTNG RESOLUTE MK4 22ARC 16.1 TUNG is CMMG’s offering in the increasingly popular 22 ARC caliber, built on their MK4 AR-15 platform. Its 16.1-inch barrel and distinctive Tungsten Cerakote finish immediately set it apart. This rifle promises a blend of accuracy, manageable recoil, and a flat-shooting trajectory, making it intriguing for both target shooting and hunting varmints.
I’ve been searching for an AR-platform rifle chambered in a modern, low-recoil cartridge suitable for extended range sessions and pest control without the significant report and cost of larger calibers. The 22 ARC seemed like a perfect fit, balancing ballistic performance with affordability.
Unboxing the RESOLUTE MK4, my first impression was of quality construction and a well-executed finish. The Tungsten Cerakote gives it a sleek, professional look, and the rifle felt solid without being excessively heavy. Compared to my existing AR-15 in 5.56 NATO and my bolt-action 22LR, the RESOLUTE MK4 seemed to occupy a sweet spot in terms of size and maneuverability.
I considered the Savage MSR 15 Competition in 224 Valkyrie and a custom AR build in 22 Nosler, but the CMMG won out due to its readily available parts, positive reputation for reliability, and the growing popularity of the 22 ARC cartridge. The rifle immediately gave off an impression of being a serious, purpose-built tool, and I was genuinely excited to get it to the range.
Real-World Testing: Putting CMMG 28B260CTNG RESOLUTE MK4 22ARC 16.1 TUNG to the Test
First Use Experience
My first outing with the RESOLUTE MK4 was at my local outdoor shooting range. The weather was clear but windy, presenting a decent challenge for testing the rifle’s accuracy and wind drift. After mounting a 3-9×40 scope I had on hand, I settled in to zero at 100 yards.
The RESOLUTE MK4 was incredibly easy to shoot; recoil was minimal, and the trigger pull was smooth and consistent right out of the box. Within a few magazines, I was consistently hitting sub-MOA groups, which was far better than I anticipated with factory ammunition. I experienced no malfunctions or feeding issues during the initial 200 rounds, despite a fairly dusty environment.
Extended Use & Reliability
After several months and well over 1000 rounds, the CMMG RESOLUTE MK4 has proven to be exceptionally reliable. I’ve used it in temperatures ranging from below freezing to over 90 degrees Fahrenheit, and it has performed flawlessly. Cleaning the rifle is simple, thanks to the AR-15 platform’s familiar disassembly.
I’ve noticed minimal wear on the bolt carrier group and other critical components, suggesting high-quality materials and construction. Compared to some budget ARs I’ve used in the past, the CMMG feels significantly more robust and capable of withstanding heavy use. It has definitely outperformed my expectations in terms of reliability and accuracy.
