CMMG 28B3D0CCG Endeavor 22 ARC 20″ Review

First Thoughts on the CMMG 28B3D0CCG Endeavor 22 ARC 20″

The CMMG 28B3D0CCG Endeavor 22 ARC 20″ is immediately striking. Chambered in the increasingly popular .22 ARC, this rifle from CMMG promises to bridge the gap between affordability, accurate long-range rimfire shooting, and AR-15 familiarity. The 20-inch barrel suggests a focus on precision and maximizing the ballistic potential of the .22 ARC cartridge, something I’m eager to explore.

I was looking for a dedicated .22 ARC rifle, specifically one built on an AR platform for consistent training and affordable practice at extended ranges. My existing .22LR rifles simply couldn’t deliver the accuracy I wanted beyond 100 yards, and centerfire ammo costs were skyrocketing.

The rifle arrived securely packaged. My initial impression was positive, the charcoal green finish is aesthetically pleasing, and the overall build felt solid. The weight distribution also seemed balanced, promising good handling.

I considered other .22 ARC options like those from Tippmann and dedicated upper receivers for existing AR platforms. However, I opted for the CMMG Endeavor for its complete rifle package, reputation for reliable .22 conversions, and the potential for out-of-the-box accuracy.

I was definitely excited. The CMMG 28B3D0CCG Endeavor 22 ARC 20″ seemed to address my specific needs perfectly, and I couldn’t wait to get it to the range.

Real-World Testing: Putting CMMG 28B3D0CCG Endeavor 22 ARC 20″ to the Test

First Use Experience

I tested the CMMG 28B3D0CCG Endeavor 22 ARC 20″ at my local shooting range, which offers distances out to 300 yards. The weather was mild, with a slight breeze, ideal for testing a rimfire rifle at longer ranges.

The rifle performed admirably. Even with inexpensive .22 ARC ammunition, I was consistently hitting steel targets at 200 yards. The action was smooth, and I experienced zero malfunctions in the first 100 rounds.

The rifle was incredibly easy to use, given the familiar AR-15 platform. The controls were intuitive, and I felt immediately comfortable behind it. The crisp trigger aided in precise shot placement.

The only surprise was the minimal recoil. It was barely perceptible, making it easy to stay on target for follow-up shots.

Extended Use & Reliability

After several months of use, including multiple range trips and a varmint hunting excursion, the CMMG 28B3D0CCG Endeavor 22 ARC 20″ has held up exceptionally well. I’ve put approximately 1000 rounds through it.

The finish shows no signs of wear, and the internal components appear to be in excellent condition. I’ve experienced only a handful of malfunctions, all of which were attributable to ammunition inconsistencies.

Cleaning is straightforward. The rifle disassembles easily, and a simple wipe-down of the bolt and barrel is usually sufficient. The CMMG platform requires minimal maintenance to keep it running smoothly.

Compared to my previous .22LR rifles, the CMMG 28B3D0CCG Endeavor 22 ARC 20″ outperforms them significantly in terms of accuracy, range, and overall reliability. This has exceeded my expectations.

Its main strength is the accuracy potential combined with the AR platform familiarity. The trigger is crisp and consistent, contributing to accurate shot placement. A potential weakness is ammunition sensitivity; it performs best with higher-quality .22 ARC rounds.
