Let’s Dive into CMMG, Inc AR-15 Action Spring
The CMMG, Inc AR-15 Action Spring is a seemingly simple component that plays a critical role in the AR-15 platform’s function. It’s manufactured by CMMG, a respected name in the firearms industry, and promises to deliver reliable performance. At a price point of just $5.89, it begs the question: does it hold up to the demands of a high-functioning AR-15?
I needed to replace a worn action spring in my go-to AR-15. Over thousands of rounds, the original spring had lost some of its tension, leading to occasional failures to feed. I was seeking a cost-effective, reliable replacement that would restore my rifle to its optimal operating condition.
Upon receiving the CMMG, Inc AR-15 Action Spring, my initial thought was that it looked like…an action spring. It was clean, properly wound, and appeared to be constructed of good-quality steel. There wasn’t any immediate cause for concern regarding its build quality.
I primarily considered action springs from Brownells and Aero Precision. I opted for the CMMG spring due to its affordability and the generally positive reputation of CMMG products. It seemed like a solid value proposition for a simple replacement part.
My first impression was cautiously optimistic. It’s an action spring – not exactly a groundbreaking piece of technology, but a vital one. I was eager to install it and see how it performed in my rifle.
Real-World Testing: Putting CMMG, Inc AR-15 Action Spring to the Test
First Use Experience
I tested the CMMG, Inc AR-15 Action Spring at my local outdoor shooting range. The weather was typical for late spring – slightly humid, with temperatures hovering around 70 degrees Fahrenheit. I ran approximately 300 rounds through my AR-15, using a mix of .223 and 5.56 NATO ammunition.
The spring performed admirably under these conditions. I experienced no failures to feed or eject, and the rifle cycled smoothly and reliably. It was a significant improvement over the worn-out spring it replaced.
Installation was straightforward, requiring no specialized tools or modifications. The spring dropped right into place, and the rifle functioned flawlessly from the first shot. My only slight concern was the initial stiffness of the spring, but that quickly subsided after the first few rounds.
Extended Use & Reliability
After several months and approximately 1500 rounds of use, the CMMG, Inc AR-15 Action Spring continues to perform reliably. I have used it in various conditions, including a dusty range environment and during a light rain shower.
There are no visible signs of wear and tear. The spring maintains its tension and continues to provide consistent cycling. I periodically clean the spring as part of my regular rifle maintenance.
Compared to my previous experiences with other aftermarket action springs, the CMMG spring has proven to be exceptionally reliable for the price. It delivers consistent performance without any noticeable degradation in function. I’d say it definitely outperforms some of the cheaper, no-name springs I’ve used in the past.
