First Impressions of Mean Arms Ejectorless ExoMag, AR-15, 32 Round Rifle Magazine
The Mean Arms Ejectorless ExoMag, AR-15, 32 Round Rifle Magazine presents a unique approach to 9mm AR-15 builds, designed to work seamlessly with bearing delay or CMMG radial delay systems, promising enhanced reliability and smooth operation. As someone who’s tinkered with countless AR-15 platforms over the last decade, I was immediately intrigued by the ejectorless design and the potential it holds for mitigating common 9mm AR feeding issues. This magazine piqued my interest as I’ve been diving into unconventional AR builds, always seeking improvements in reliability and performance.
For years, I’ve struggled with the inherent challenges of adapting the AR-15 platform for 9mm, a cartridge it wasn’t originally designed for. Many 9mm AR builds suffer from feeding problems related to the magazine adapter and the interaction with the bolt. The Mean Arms ExoMag aims to eliminate these issues by integrating directly with specific delayed blowback systems and removing the standard AR-15 ejector, creating a dedicated and streamlined 9mm AR magazine solution.
Upon unboxing, the ExoMag felt solid and well-constructed. The injection-molded polymer felt durable, comparable to other high-quality magazines on the market, and the 32-round capacity was a welcome sight. My initial thought was that it looked and felt like a standard AR magazine with the crucial omission of the ejector engagement features.
Compared to standard Glock magazine-compatible AR-9 magazines or Colt-style stick magazines, the ExoMag stood out due to its stated compatibility with the Mean Arms or CMMG systems without needing an adapter. This direct integration promised improved feeding and reliability and played a significant role in my decision to test it. I was eager to see if it lived up to the claims of improved reliability and consistent function within a dedicated 9mm AR build. I am excited, but somewhat cautiously optimistic.
Real-World Testing: Putting Mean Arms Ejectorless ExoMag, AR-15, 32 Round Rifle Magazine to the Test
First Use Experience
My first test of the Mean Arms Ejectorless ExoMag, AR-15, 32 Round Rifle Magazine took place at my local shooting range. I paired it with a 9mm AR-15 featuring a CMMG radial delayed blowback system, the setup for which it was specifically designed. The initial loading of the magazine was straightforward, with the rounds seating smoothly and the high-tensile steel spring providing consistent pressure.
I ran through several magazines, alternating between various 9mm ammunition types, including hollow points. In dry conditions, the magazine fed reliably with no failures to feed or eject during the first 100 rounds. This was a promising start, especially considering the known issues I’ve experienced in the past with other 9mm AR magazine setups.
Extended Use & Reliability
After several months and hundreds of rounds, the Mean Arms Ejectorless ExoMag has proven to be a reliable component within my dedicated 9mm AR-15 build. There are minimal signs of wear and tear on the polymer body, and the spring tension remains consistent. I clean the magazine after each range visit, which involves disassembling it and wiping down the internal components; it’s a simple and straightforward process.
Compared to my prior experiences with standard 9mm AR magazines that required adapters, the Mean Arms ExoMag significantly outperformed them in terms of reliability and consistent feeding. I’ve experienced virtually no malfunctions related to the magazine itself, a testament to its design and integration with delayed blowback systems. In my experience, it has greatly reduced the number of malfunctions encountered while shooting.
