Let’s Dive into CMMG, Inc AR15 Spring, Ejection Port Cover
The CMMG, Inc AR15 Spring, Ejection Port Cover might seem like a minor component, but it plays a critical role in protecting the AR-15’s internal workings from debris. A functioning ejection port cover ensures reliability and prevents malfunctions, especially in harsh environments. This little spring is vital for keeping that cover doing its job.
After years of shooting and maintaining AR-15s, I’ve learned that even the smallest parts can cause major headaches if they fail. My ejection port cover spring had seen better days, resulting in a loose cover that flapped open at inopportune moments. I needed a reliable replacement, and the CMMG, Inc AR15 Spring, Ejection Port Cover seemed like a simple, affordable solution.
Upon receiving the spring, my initial impression was that it was… well, a spring. Its diminutive size belies its importance. The material appeared to be of decent quality, exhibiting a reassuring level of tensile strength. It looked nearly identical to the original, so I was optimistic about a straightforward install.
Compared to potentially upgrading the entire ejection port cover assembly with aftermarket options (which can run upwards of $20), replacing just the spring felt like a cost-effective and practical first step. I’ve used springs from other manufacturers in the past, but CMMG has a reputation for producing quality AR parts, giving me confidence in this product. My first thought? “Let’s see if this tiny thing can solve my problem!”
Real-World Testing: Putting CMMG, Inc AR15 Spring, Ejection Port Cover to the Test
First Use Experience
My first testing ground for the CMMG, Inc AR15 Spring, Ejection Port Cover was at my workbench, which is basically my “gun-tinkering” range. Installation, as many AR enthusiasts know, can be a bit fiddly. This isn’t the spring’s fault, per se, but it’s part of the overall experience.
The initial attempt to seat the spring proved challenging. The spring has a very strong desire to spring back out. Once I wrestled it into place, however, the ejection port cover snapped shut with satisfying authority.
Extended Use & Reliability
After several range trips spanning a couple of months, the CMMG, Inc AR15 Spring, Ejection Port Cover has proven to be a reliable, albeit small, hero. There are no signs of weakening or wear, and the ejection port cover continues to function flawlessly. The spring’s robust design inspires confidence, assuring me that it will withstand the rigors of regular use.
Cleaning and maintenance are nonexistent for this part; it either works, or it doesn’t. This little spring has certainly outperformed my expectations, especially given its low cost. It’s a testament to the fact that sometimes the simplest solutions are the most effective.
