I considered other options, including modified Glock magazines and alternative AR-9 magazine designs. Ultimately, I chose the Mean Arms ExoMag due to its specific design for delayed blowback systems and the MEAN Arms reputation for quality. Initial impressions were positive and instilled confidence.

Real-World Testing: Putting Mean Arms Ejectorless ExoMag, AR-15, 15 Round Rifle Magazine to the Test

First Use Experience

I tested the Mean Arms Ejectorless ExoMag at my local outdoor range, using my AR-9 pistol build with a CMMG radial delayed blowback system.
