The CMMG Endeavor 22 ARC 20″ Made a Bold First Impression
The CMMG Endeavor 22 ARC 20″ is not your average .22LR AR-pattern rifle. It’s a dedicated platform designed for accuracy, reliability, and a whole lot of fun. CMMG has built a reputation for quality AR components and complete firearms, and the Endeavor 22 ARC promises to deliver that same level of performance in a .22LR package.
I was searching for a dedicated .22LR rifle that mirrored the AR-15 platform for training purposes. I wanted something that would allow me to practice my fundamentals without the expense and recoil of centerfire ammunition. Several dedicated .22LR AR-pattern rifles were considered, but the CMMG name and reputation for their .22LR conversion bolts ultimately swayed my decision towards the CMMG Endeavor 22 ARC 20″.
Upon unboxing, the CMMG Endeavor 22 ARC 20″ immediately impressed with its solid feel and AR-like ergonomics. The rifle felt well-balanced. The fit and finish were excellent. I was excited to finally get it out to the range.
The CMMG Endeavor 22 ARC 20″ stands out compared to the Smith & Wesson M&P 15-22 Sport and the Tippmann Arms M4-22. While both the S&W and Tippmann are fantastic rifles, the CMMG Endeavor 22 ARC 20″ felt like a step up in terms of overall build quality and the potential for customization. The CMMG utilizes a true AR upper and lower receiver. It accepts standard AR-15 handguards and stocks, unlike the M&P 15-22, which has proprietary components. My first impression was a mix of excitement and anticipation. I knew I had a quality piece of equipment in my hands.
Real-World Testing: Putting CMMG Endeavor 22 ARC 20″ to the Test
First Use Experience
I tested the CMMG Endeavor 22 ARC 20″ at my local outdoor shooting range. The range offered distances out to 100 yards. The weather was sunny and mild, ideal conditions for a first outing. I primarily used CCI Mini-Mag ammunition, a reliable standard for .22LR rifles.
The rifle performed flawlessly. I experienced zero malfunctions in the first 200 rounds. The trigger felt crisp and consistent. The CMMG Endeavor 22 ARC 20″ was incredibly easy to use, requiring no real adjustment period.
The only surprise was how quiet the rifle was, even without a suppressor. The 20″ barrel seemed to maximize the efficiency of the .22LR cartridge. It minimized the report.

I have put thousands of rounds through it, using a variety of .22LR ammunition types from budget bulk ammo to match-grade target rounds. I’ve only experienced the occasional malfunction with the cheapest, dirtiest ammunition.
Durability has not been an issue. The finish is holding up well. There are no signs of significant wear and tear. The CMMG Endeavor 22 ARC 20″ is easy to clean. The direct blowback system gets dirty, but disassembly and cleaning are straightforward.
