If you're converting your AR-15 to 9mm, the ExoMag gives you the simplicity that magwell adapters and conversion kits can't match. This is a dedicated 9mm magazine built from the ground up, not a retrofit or conversion. It uses the same STANAG outer dimensions as standard rifle magazines, so it drops into your existing lower with zero fuss. You keep your 5.56 lower exactly as it is—no modifications, no special tools, and you can swap back to rifle caliber uppers anytime.
The ejector is the key piece here. On standard 9mm conversions, you either deal with compatibility headaches between different bolt carrier group types or you pay a bunch to adapt your setup. This magazine solves that with a metal-tipped ejector built right into the feed lips. It's designed specifically for standard blowback bolts and consistently handles all 9mm ammo types, including hollow points. The long, straight feed ramp funnels rounds into the chamber without the finicky behavior you sometimes see with converted magazines.
The ExoMag feels instantly familiar because it handles exactly like a standard AR magazine. Your reload technique stays the same, your muscle memory carries over, and you can use your existing mag pouches and storage solutions. The magazine comes fully assembled and ready to go. The injection-molded polymer construction is durable and resists corrosion, while the high-tensile steel spring and polymer follower keep everything running smoothly through hard use. Because the 9mm cartridge is shorter than 5.56, you'll notice the mag sits visually different in your well, making it immediately obvious which caliber you're running.
Just like a proper AR-15 should function, the ExoMag includes a last round bolt-hold-open feature for faster reloads and better range awareness.
Yes. The ExoMag fits standard STANAG-profile lower receivers without any modifications. It drops in just like a regular rifle magazine. You don't need adapters, drilling, or special tools. As long as your lower accepts standard AR magazines, the ExoMag will function.
This is the ejector version, designed for standard blowback 9mm uppers using Glock or Colt variant bolt carrier groups. The ejectorless version is specifically for bearing delay systems and CMMG radial delay platforms, which have the ejector built into the bolt itself. Use the ejector version if you're running a standard blowback 9mm upper.
It does. The magazine is compatible with all 9mm Luger ammunition, including full metal jacket, hollowpoint, and various factory loads. Customers consistently report reliable feeding with different ammo brands without any pickiness.
Yes. Since the ExoMag uses STANAG outer dimensions and fits in your existing magwell, it works with standard AR magazine pouches, carriers, and storage accessories you already have. The main visual difference is that the 9mm cartridge is shorter than 5.56, so the magazine will sit visually different in your well.
