First Thoughts on the CMMG Resolute 22 ARC 16.10″ Upper Receiver 7075-T6 Aluminum 15″ M-LOK Handguard
The CMMG Resolute 22 ARC 16.10″ Upper Receiver promises to deliver an affordable and reliable .22 ARC option for the AR-15 platform. CMMG is known for its innovative rimfire conversions and dedicated .22LR AR-15 platforms. This upper receiver aims to bring that same level of reliability and fun to the new .22 ARC cartridge.
I was looking for a dedicated .22 ARC upper receiver to extend the range of my AR-15 platform while maintaining low recoil and cost-effective training. Most .22LR conversions lack the accuracy for longer distances, so the .22 ARC seemed like a natural step up. I was intrigued by the potential for accurate, affordable long-range rimfire shooting.
The CMMG Resolute 22 ARC arrived in a standard cardboard box, well-protected with foam inserts. My initial impression was positive; the Sniper Gray Cerakote finish looked clean and professional. The 15″ M-LOK handguard felt solid and provided ample space for accessories.
Compared to other .22LR conversion kits and complete uppers, like the CMMG .22LR AR Conversion Kit or the Tippmann Arms M4-22, the Resolute 22 ARC promised a more dedicated and accurate platform. I chose the CMMG Resolute 22 ARC because I wanted to take advantage of the improved ballistic performance of the .22 ARC cartridge. I hoped for better accuracy and a flatter trajectory compared to the .22LR options.
I was excited to test out the CMMG Resolute 22 ARC. The upper receiver felt well-built, and the potential for long-range .22 ARC shooting was enticing. I was eager to see how it would perform at 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 tested the CMMG Resolute 22 ARC at my local outdoor shooting range. The weather was clear and sunny, around 75 degrees Fahrenheit. I mounted the upper receiver onto a standard AR-15 lower with a mil-spec trigger and buffer.
The initial range session involved zeroing the optic at 50 yards. The upper cycled reliably with the recommended ammunition. I experienced a few failures to extract in the first 50 rounds, but this cleared up as the rifle broke in.
The CMMG Resolute 22 ARC was surprisingly accurate out of the box. I achieved groupings of around 1.5 inches at 50 yards with ease. It was relatively easy to get used to the upper receiver. The controls are identical to a standard AR-15, making it a seamless transition.
Extended Use & Reliability
After several months of use, the CMMG Resolute 22 ARC has held up well. I have put approximately 1000 rounds through it. The Cerakote finish still looks new, with no visible signs of wear.
The upper receiver has proven to be reliable. The initial extraction issues disappeared after the break-in period. Maintenance is straightforward; a quick cleaning after each range session is all it takes.
Compared to my experiences with .22LR AR conversions, the CMMG Resolute 22 ARC is a significant step up in terms of accuracy and reliability. It outperformed my expectations for a dedicated .22 ARC upper. The rifle allows consistent hits on steel targets out to 200 yards, something I couldn’t consistently achieve with a .22LR conversion.
