Let’s Dive into CMMG Bolt Carrier Assembly
The CMMG Bolt Carrier Assembly is a critical component in any AR-15 rifle, responsible for cycling rounds and ensuring reliable operation. Manufactured by CMMG, a reputable name in the firearms industry, this assembly promises quality and performance. I decided to investigate this specific bolt carrier assembly because I was experiencing cycling issues with my current AR-15 build.
My rifle was short-stroking, and I suspected the bolt carrier group might be the culprit. I wanted a reliable, high-quality replacement that wouldn’t break the bank. Upon receiving the CMMG Bolt Carrier Assembly, my initial impression was positive. The phosphate finish looked clean and even, and the staking on the gas key appeared robust.
Compared to a cheaper, no-name bolt carrier assembly I had previously used, the CMMG felt significantly more substantial. I also considered a bolt carrier group from Bravo Company Manufacturing (BCM) and Daniel Defense, but ultimately chose the CMMG for its balance of quality and price. My first impression was one of cautious optimism; I was eager to see if it would resolve my rifle’s issues and live up to its promise of reliability.
Real-World Testing: Putting CMMG Bolt Carrier Assembly to the Test
First Use Experience
I first tested the CMMG Bolt Carrier Assembly at my local outdoor shooting range. The weather was typical for a summer afternoon – hot and dusty, conditions that can easily exacerbate any existing problems. Installing the bolt carrier was simple and straightforward, dropping right into my AR-15 upper receiver. From the very first shot, I noticed a significant improvement in cycling smoothness compared to my previous bolt carrier.
The short-stroking issue I had been experiencing seemed to vanish immediately. There were no malfunctions, even after running several magazines through the rifle. I was pleasantly surprised by the immediate and noticeable improvement in performance.
Extended Use & Reliability
After several months of consistent use, the CMMG Bolt Carrier Assembly has continued to perform flawlessly. I’ve put approximately 1,000 rounds through the rifle since installing the CMMG, across various ammunition brands and grain weights. The assembly shows no signs of significant wear and tear. Cleaning and maintaining the CMMG is also relatively easy.
A quick wipe-down with CLP after each range session keeps it running smoothly. Compared to my earlier frustrations with the previous bolt carrier, the CMMG has been a significant upgrade. The increased reliability and smooth cycling have significantly improved my shooting experience.
