Mean Arms Exomag 9mm Luger 10 Round Ejectorless Black

The Mean Arms Exomag 9mm Luger 10 round ejectorless magazine is built for AR shooters who want to run 9mm without swapping lowers or wrestling with adapter plates. This 10-round magazine uses a standard STANAG profile, so it fits your existing AR platform unchanged—just swap the upper to 9mm and you're done. The ejectorless design is specifically engineered for delay-blowback systems like the Mean Arms Bearing Delay or CMMG Radial Delay BCGs, ensuring reliable feeding and function with those platforms.

If you're already trained on AR controls and muscle memory, the Exomag keeps things simple. It handles any 9mm load you feed it—target rounds, hollow points, whatever's in the ammo can. The last-round bolt-hold-open feature works just like your 5.56 rifle, so reloads feel natural and your training translates directly. Because it's a true STANAG magazine, you can keep using your existing mag pouches, range bags, and storage racks without buying new kit.

Assembly is complete out of the box—no tools, no fiddling. The polymer construction is purpose-built for reliable feeding, and the magazine comes ready to load and shoot. Switching from .223 to 9mm now means changing your upper receiver, period. No modifications to your lower, no proprietary parts, no complications.

Frequently Asked Questions

Will this magazine work with standard blowback 9mm uppers?

No. The ejectorless version is designed specifically for delay-blowback systems like the Mean Arms Bearing Delay and CMMG Radial Delay. If you're running a standard blowback 9mm BCG, you'll need the ejector version instead.

Do I need to modify my lower receiver to use this magazine?

No. The Exomag uses a STANAG profile, so it drops into your standard AR lower receiver without any modifications. Simply swap your upper to 9mm and you're ready to go.

Can I use my existing AR magazine pouches and accessories?

Yes. Because the Exomag maintains the STANAG profile and dimensions, it works with standard AR mag pouches, storage racks, and other STANAG-compatible accessories you already own.

What types of 9mm ammunition does this magazine feed?

The Exomag handles all common 9mm Luger ammunition, including target rounds and hollow points. It's designed to be reliable with whatever 9mm load you choose.
