The CMMG Resolute 22 ARC 16.10″ Upper Receiver 7075-T6 Aluminum 15″ M-LOK Handguard Made a Bold First Impression
The CMMG Resolute 22 ARC 16.10″ Upper Receiver 7075-T6 Aluminum 15″ M-LOK Handguard isn’t just another AR-15 upper; it’s a dedicated 22 ARC platform designed for precision and versatility. Crafted by CMMG, this upper promises to deliver consistent performance and accuracy in a lightweight, adaptable package. It was a unique approach to a training platform that genuinely sparked my interest.
My search began when I needed a dedicated AR platform for affordable, high-volume training. 5.56 ammo costs were skyrocketing, and I wanted something that mirrored the feel of my primary rifle without breaking the bank. The ability to use readily available .22 ARC ammunition was a significant draw.
The CMMG Resolute 22 ARC arrived in a surprisingly compact box. My initial impressions were positive; the Sniper Gray Cerakote finish looked fantastic, and the 15″ M-LOK handguard felt solid. The weight was noticeably lighter than my standard 5.56 upper, a welcome change for extended range sessions.
I was also considering a dedicated .22LR AR upper, but I found them to be unreliable and finicky. The CMMG promised better reliability and accuracy with the .22 ARC cartridge. A 9mm PCC was another option, but it didn’t offer the same manual of arms as my AR-15, making the CMMG Resolute the clear winner.
I was immediately excited by the build quality and the potential for cost-effective training. The sleek design and M-LOK handguard made it feel like a premium product. It looked like it would offer a fun and effective solution for my training needs.
Real-World Testing: Putting CMMG Resolute 22 ARC 16.10″ Upper Receiver 7075-T6 Aluminum 15″ M-LOK Handguard to the Test
First Use Experience
I first tested the CMMG Resolute 22 ARC at my local outdoor shooting range. I mounted it on a standard AR-15 lower receiver with a mil-spec trigger and used a variety of .22 ARC ammunition from different manufacturers. The weather was clear and sunny, with a slight breeze.
The upper functioned flawlessly out of the box, with no malfunctions in the first 200 rounds. The recoil was minimal, making it easy to maintain sight picture and rapidly acquire targets. The CMMG Zeroed Muzzle Brake effectively mitigated any muzzle rise, further enhancing the shooting experience.
It took very little time to get used to the CMMG Resolute 22 ARC. The controls are identical to a standard AR-15, making the transition seamless. The lighter weight also contributed to improved handling and maneuverability.
I was initially surprised by the accuracy of the .22 ARC round, consistently hitting targets at 50 yards. The reliability of the system was also a pleasant surprise, especially compared to the .22LR AR conversions I had tried in the past. It made me very confident with the potential of this rifle.
Extended Use & Reliability
After several weeks and over 1000 rounds, the CMMG Resolute 22 ARC continues to impress. The reliability has been exceptional. I’ve experienced only a handful of malfunctions, mostly attributable to a specific brand of ammunition.
There are minimal signs of wear and tear on the Sniper Gray Cerakote finish. The 7075-T6 Aluminum receiver and 4140 Steel barrel have held up remarkably well under constant use. The M-LOK handguard remains solid and secure.
Cleaning the CMMG Resolute 22 ARC is straightforward. A quick wipe-down of the bolt and barrel is usually sufficient. The .22 ARC cartridge is relatively clean-burning. It’s much easier to maintain than my direct impingement 5.56 AR-15.
Compared to my previous attempts at .22LR conversions, the CMMG Resolute 22 ARC is in a different league. It provides the same ergonomics and feel as my go-to rifle, at a fraction of the cost. It has become an indispensable part of my training regime.
