The CMMG Inc. Dissent Mk4 – 22Arc – Sniper Gray 6061-T6 Aluminum Made a Bold First Impression
The CMMG Inc. Dissent Mk4 – 22Arc – Sniper Gray 6061-T6 Aluminum is not your average AR-platform firearm. This sleek, Sniper Gray beauty chambers the relatively new .22 ARC cartridge and promises a unique blend of accuracy and maneuverability, built around the reliable Mk4 platform. After spending over a decade immersed in the world of tactical gear and firearms, I was particularly drawn to the Dissent’s innovative design and the potential of the .22 ARC caliber.
My search began when I sought a lightweight, accurate, and easily transportable rifle for varmint hunting and recreational target shooting. I wanted something quieter and with less recoil than my standard AR-15, but still offering decent range and terminal performance. The CMMG Dissent immediately stood out for its compact design and the promise of the .22 ARC’s flat trajectory and surprising energy.
Upon unboxing the Dissent, I was immediately struck by the quality of the finish and the solid feel of the 6061-T6 aluminum receiver. The Sniper Gray Cerakote was flawless, and the rifle felt well-balanced in my hands. It was lighter than I anticipated, which further fueled my excitement.
I considered options like the Sig Sauer MCX Rattler PCB in .223, but its price point and louder report made it less appealing for my needs. A dedicated .22 LR AR build was also considered, but the ballistics of the .22 ARC won me over. Initial impressions were overwhelmingly positive; the CMMG Dissent felt like a serious piece of kit, hinting at the performance I hoped to experience on the range.
Real-World Testing: Putting CMMG Inc. Dissent Mk4 – 22Arc – Sniper Gray 6061-T6 Aluminum to the Test
First Use Experience
I took the CMMG Inc. Dissent Mk4 – 22Arc – Sniper Gray 6061-T6 Aluminum to my local shooting range, which offers both indoor and outdoor facilities. I tested it primarily on the outdoor range at distances from 25 to 100 yards. The weather was slightly overcast with a light breeze – typical conditions for my area.
The Dissent proved exceptionally easy to use from the get-go. Its controls were intuitive, mirroring the AR-15 platform, which made transitioning seamless. The first few shots were surprisingly quiet, a definite plus for varmint hunting near residential areas. After the first magazine, I was very impressed.
There was a minor issue with the initial magazine not seating properly, requiring a firm tap to lock in. After that initial hiccup, I experienced no further malfunctions.
Extended Use & Reliability
After several weeks of consistent use, the CMMG Dissent has proven to be a reliable and enjoyable firearm. I’ve put approximately 500 rounds through it without any significant issues. The finish has held up well, with no noticeable wear and tear.
Maintaining the Dissent is simple; a standard AR-15 cleaning kit works perfectly. Cleaning the bore is straightforward, and the action is easily accessible for lubrication. Compared to my experience with other rimfire platforms, the CMMG Dissent is significantly easier to clean.
It has exceeded my expectations. It’s more accurate than I anticipated for a relatively short-barreled platform and the .22 ARC round delivers consistent performance at various distances. It’s my new go-to for casual range days and small game hunts.
