CMMG 28B3D0CCT ENDEAVOR MK4 22ARC 20 COYTN Review

First Impressions of CMMG 28B3D0CCT ENDEAVOR MK4 22ARC 20 COYTN

The CMMG 28B3D0CCT ENDEAVOR MK4 22ARC 20 COYTN is an intriguing offering from CMMG, promising a blend of AR-platform ergonomics with the unique capabilities of the 22 ARC cartridge. As a seasoned outdoor and tactical gear specialist, I’ve seen countless AR variants, but the 22 ARC chambering piqued my interest immediately. Its potential for longer-range varmint hunting and target shooting in a lightweight package promised something special, a niche between a dedicated AR-15 and a traditional rimfire rifle.

I’ve been searching for a lightweight, accurate platform for coyote and prairie dog hunting that wouldn’t break the bank on ammunition costs. The 22 ARC seemed like a perfect fit, offering a flatter trajectory and higher velocities than .223 in similar grain weights, while using a smaller powder charge. My initial excitement stemmed from the potential versatility: a rifle capable of dispatching varmints at extended ranges while also being fun and affordable to plink with at the range.

Upon unboxing, the rifle presents a clean and modern aesthetic. The Coyote Tan finish is evenly applied and visually appealing, hinting at a durable coating beneath. The rifle felt well-balanced in my hands, although I noted that the lack of an included magazine was a slight disappointment given the price point.

Compared to my existing AR-15 in .223 Wylde and a dedicated .22 LR AR-platform, the CMMG ENDEAVOR MK4 22ARC seemed to strike a balance between the two. The .223 offered more raw power, while the .22 LR was far cheaper to shoot, but the 22 ARC promised a compromise – a flatter-shooting, longer-range varmint round that wouldn’t bankrupt me during a weekend outing. I chose the CMMG model specifically because of CMMG’s reputation for quality AR components and the unique appeal of the 22 ARC chambering in an AR platform.

My first impression was one of cautious optimism. The rifle looked and felt well-made, but the true test would be in its performance at the range. I was both excited and slightly apprehensive, hoping that the CMMG 28B3D0CCT ENDEAVOR MK4 22ARC 20 COYTN would live up to its promise.
