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 is more than just another rimfire upper; it’s a gateway to affordable, high-volume training and plinking within the familiar AR-15 platform. CMMG has carved a niche for themselves by offering reliable .22LR conversion kits and dedicated uppers, and the Resolute 22 ARC aims to be their flagship offering. With its 7075-T6 aluminum receiver, 15″ M-LOK handguard, and dedicated 22 ARC chambering, it promises accuracy, modularity, and a serious dose of fun without breaking the bank.
My search for this upper began with the desire to drastically reduce my training costs. Centerfire ammo prices have skyrocketed, making frequent range trips a luxury, and I needed a cost-effective way to maintain proficiency with my AR platform. I also wanted something more accurate than a simple .22LR conversion kit, thus began my search for a dedicated 22 ARC upper.
The CMMG Resolute 22 ARC arrived well-packaged. The Sniper Gray Cerakote finish immediately impressed me; it’s a durable and aesthetically pleasing coating. The 15″ M-LOK handguard felt solid and provided ample real estate for accessories.
I considered the Tippmann Arms M4-22 and the Smith & Wesson M&P 15-22, but I ultimately chose the CMMG Resolute 22 ARC for its modularity and compatibility with my existing AR lower receiver. The full compatibility with AR lowers sealed the deal. I wanted the exact same trigger feel.
My initial impression was overwhelmingly positive. The upper felt robust and well-made, with no visible flaws. I was genuinely excited to see how it performed on the range.
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. The weather was clear and mild, providing ideal conditions for accuracy testing. I used a variety of .22LR ammunition brands and grain weights to gauge its performance.
The upper functioned flawlessly right out of the box. I experienced no failures to feed or extract. Even with cheaper bulk ammunition, the CMMG Resolute 22 ARC cycled reliably.
The ease of use was immediately apparent. Simply swapping out my existing upper for the CMMG Resolute 22 ARC was a breeze. No special tools or adjustments were required.
The only slight surprise was the difference in recoil. Compared to my .223 Wylde upper, the 22 ARC offers practically no recoil. However, this made it ideal for introducing new shooters to the AR platform.
Extended Use & Reliability
After several months of regular use, the CMMG Resolute 22 ARC continues to impress me. I estimate I’ve put well over 2,000 rounds through it without any major issues. The durability has also proven to be excellent.
There are no noticeable signs of wear and tear beyond some minor cosmetic scuffs on the finish. The Cerakote seems to be holding up well to regular use and cleaning. Regular cleaning is a must with rimfire cartridges.
The CMMG Resolute 22 ARC is relatively easy to clean and maintain. The bolt is easily accessible, and the barrel can be cleaned with standard cleaning tools. I make sure to clean the chamber and bolt face thoroughly after each range session to prevent build-up.
This upper far outperforms my previous .22LR conversion kit. The accuracy is significantly better, and the overall shooting experience is much more enjoyable. It’s now my go-to upper for training and recreational shooting.
