CMMG, Inc 22ARC Barrel Collar Assembly Review

Let’s Dive into CMMG, Inc 22ARC Barrel Collar Assembly

The CMMG, Inc 22ARC Barrel Collar Assembly is a seemingly small, unassuming piece of stainless steel, yet it’s the keystone for unlocking true .22LR performance from your AR-15. Made by CMMG, a reputable name in AR platform accessories, this collar replaces the standard chamber adapter on your existing .22LR AR conversion bolt group. This simple swap allows the bolt group to function correctly with a dedicated .22LR barrel, which dramatically improves accuracy and reliability.

I stumbled upon this product while battling consistent failures and subpar accuracy with my .22LR conversion kit in my AR-15. I enjoyed the idea of cheap practice, but the conversion kit never quite lived up to my expectations regarding precision and reliability. After extensive online research, the CMMG 22ARC Barrel Collar Assembly emerged as the solution to transform my multi-caliber AR into a dedicated, accurate .22LR platform.

Upon receiving the CMMG, Inc 22ARC Barrel Collar Assembly, I was immediately impressed by the clean machining and solid feel of the stainless steel. It was a simple, robust design and it inspired confidence. Comparing it to the original chamber adapter, the CMMG part appeared to be manufactured to tighter tolerances, which I hoped would translate into better performance. I initially considered other complete .22LR upper receivers, but the CMMG collar allows me to utilize my existing bolt and magazines, making it a more cost-effective solution.

My first impression was one of cautious optimism. While seemingly insignificant, the potential for this small component to transform my AR’s .22LR performance had me excited to get it installed and tested. The promise of improved accuracy and reliability was exactly what I was looking for.

Real-World Testing: Putting CMMG, Inc 22ARC Barrel Collar Assembly to the Test

First Use Experience

My first test took place at my local outdoor shooting range.
