Real-World Testing: Putting CMC Triggers BBL-556-002 AR Barrel 5.56 NATO 10.50″ Black Nitride/Chrome Moly Vanadium Steel Barrel to the Test

First Use Experience

I tested the CMC Triggers barrel at my local shooting range, an outdoor facility with distances out to 300 yards. The weather was clear but cool, around 50 degrees Fahrenheit, and there was a slight breeze. I used a variety of ammunition, including Federal 55-grain FMJ, Hornady 75-grain BTHP, and some PMC Bronze 55-grain FMJ, to assess the barrel’s performance with different loads.

Initially, I focused on zeroing the optic at 50 yards; the process was surprisingly quick, indicating a consistent and accurate barrel. I experienced no issues with cycling or extraction, even with the various ammunition types. The 1:7″ twist rate seemed to stabilize the heavier 75-grain rounds exceptionally well.

There were no significant issues, though I did notice a slightly increased muzzle flash compared to my 16-inch barrel, which is expected with a shorter barrel. The sound was also noticeably louder, reinforcing the importance of proper hearing protection.

Extended Use & Reliability

After several months of regular use, the CMC Triggers BBL-556-002 AR Barrel 5.56 NATO 10.50″ Black Nitride/Chrome Moly Vanadium Steel Barrel has proven to be remarkably reliable. It has seen around 1000 rounds without any malfunctions or degradation in accuracy. I’ve taken it through several training sessions, including some dynamic shooting drills, and it has performed flawlessly.

The Black Nitride finish has held up remarkably well, showing no signs of wear despite being exposed to various conditions. Cleaning the barrel is straightforward; carbon fouling wipes away easily, and there’s no evidence of corrosion or pitting. Regular cleaning and lubrication are all that’s needed to keep it running smoothly.

Having used other short-barreled ARs in the past, I can confidently say that the CMC Triggers barrel outperforms many of them in terms of accuracy and consistency. Its performance is a testament to the quality of the materials and the precision of the manufacturing process.
