CMMG AR-15/MK4 MAGAZINE – BLACK, 22LR, 25/RD 041D0032 Review

First Impressions of CMMG AR-15/MK4 MAGAZINE – BLACK, 22LR, 25/RD 041D0032

The CMMG AR-15/MK4 MAGAZINE – BLACK, 22LR, 25/RD 041D0032 promises to bring reliable .22LR feeding to your AR platform, whether you’re using a dedicated .22LR upper or a conversion kit. CMMG has a reputation for quality AR components, and this magazine aims to extend that reputation into the rimfire realm with a durable, high-capacity option. This magazine offers a potential solution for affordable training and recreational shooting with your existing AR-15 lower receiver.

I needed a reliable magazine for my AR-15 .22LR conversion kit to reduce malfunctions and improve training sessions with my family. I was consistently frustrated with other, less reputable magazines that caused frequent jams and misfeeds, ultimately diminishing the training experience. I wanted something that could hold a decent amount of rounds while maintaining reliable feeding.

My first impression upon unboxing the CMMG magazine was positive; the black polymer felt robust and well-molded. The spring tension felt firm, indicating a quality build. The weight of the magazine felt appropriate for its capacity, not flimsy or cheap.

I considered the Black Dog Machine magazines, which are another popular option for .22LR AR conversions, as well as some cheaper generic brands. Ultimately, I chose the CMMG magazine because of CMMG‘s solid reputation for AR parts and the magazine’s promise of compatibility with both conversion kits and dedicated Mk4 lowers. I was hoping for better reliability and durability than what the cheaper options offered.

Initially, I felt optimistic about the magazine’s potential to solve my reliability issues and provide a smoother shooting experience. I was eager to test it out at the range. I was pleasantly surprised by its seemingly robust build quality compared to some other .22LR magazines I’ve used.

Real-World Testing: Putting CMMG AR-15/MK4 MAGAZINE – BLACK, 22LR, 25/RD 041D0032 to the Test

First Use Experience

I tested the CMMG magazine at my local outdoor shooting range on a clear, slightly breezy day. I used it with a CMMG .22LR AR-15 conversion kit in my standard mil-spec AR-15 lower. I fired approximately 200 rounds of CCI Mini-Mags through the magazine during this initial session.

The magazine performed admirably, even when slightly dusty after being laid on the range bench. I didn’t experience any feeding issues or jams during the entire session. The rounds chambered smoothly and consistently, which was a significant improvement compared to my previous magazines.

The magazine was easy to load, although it requires a bit of pressure to get the last few rounds in. It locked into the lower receiver securely and released cleanly. No tools were needed.

I experienced zero malfunctions with the CMMG magazine during the first range trip. This was a welcome change from the frequent stoppages I had become accustomed to. I was very pleased with the initial performance.

Extended Use & Reliability

After several months of using the CMMG magazine across multiple range sessions and informal plinking outings, it has held up exceptionally well. I’ve put approximately 1000 rounds through it at this point. Reliability has remained consistently high, with only a handful of malfunctions that were likely attributable to ammunition rather than the magazine itself.

The magazine shows no significant signs of wear and tear, despite being used regularly. The polymer body remains intact, and the spring tension feels just as strong as when it was new. The finish has held up well to minor bumps and scratches.

Cleaning the magazine is straightforward: I simply disassemble it and wipe down the components with a clean cloth. I occasionally use a brush to remove any stubborn residue. Reassembly is easy and intuitive.

Compared to my previous experiences with unreliable .22LR magazines, the CMMG magazine has been a game-changer. It has significantly improved the overall shooting experience, making plinking and training sessions far more enjoyable and productive. It far outperforms the cheaper, generic magazines I have used in the past.
