CMMG Inc. Endeavor MK4 22ARC – Coyote Review

First Thoughts on the CMMG Inc. Endeavor MK4 22ARC – Coyote

The CMMG Inc. Endeavor MK4 22ARC – Coyote arrives on the scene promising a blend of AR-platform familiarity with the economical and low-recoil benefits of the 22 ARC cartridge. From CMMG, a manufacturer known for its innovative approach to firearms, the Endeavor MK4 series aims to deliver a versatile and accurate shooting experience. It piqued my interest because I’ve been looking for a dedicated platform for training new shooters, especially younger ones, without sacrificing the AR-15 manual of arms.

The CMMG Inc. Endeavor MK4 22ARC – Coyote enters the market as an alternative to dedicated .22LR AR platforms, or converting existing AR-15s to .22LR, potentially offering greater accuracy and reliability with its proprietary 22 ARC chambering. I previously used a .22LR conversion kit for my AR-15, which worked okay, but suffered from inconsistent cycling and accuracy issues. My decision to explore the CMMG Inc. Endeavor MK4 22ARC – Coyote stemmed from a need for a more purpose-built .22 ARC rifle.

Unboxing the rifle revealed a visually appealing firearm, sporting the coyote tan finish that gives it a tactical yet subdued look. The weight felt well-balanced, and the overall build quality seemed solid, indicating attention to detail by CMMG. The initial impression was positive, exceeding expectations given the price point of $813.49.

Compared to the Smith & Wesson M&P 15-22 and the Tippmann Arms M4-22, both popular .22LR AR-style rifles, the CMMG Inc. Endeavor MK4 22ARC – Coyote stood out for its promise of superior accuracy and the unique 22 ARC caliber, as well as the coyote tan finish. I chose it hoping for a more refined shooting experience, closer to a standard AR-15. My initial excitement outweighed any reservations, and I couldn’t wait to get it to the range.
