The MEAN Arms ExoMag Ejector 9mm 40-Round Magazine is built to keep the fun (and firepower) going strong. Made from tough, lightweight polymer, this mag packs 40 rounds of 9mm punch into a sleek, high-capacity design that’s perfect for range days or home defense setups. It works seamlessly with standard AR-15 lowers paired with a 9mm upper and blowback BCG—no adapters, no nonsense.
A built-in ejector ensures clean cycling, while the last-round bolt-hold open feature keeps things running just the way you expect. The polymer follower feeds all your favorite 9mm loads, including hollow points, without a hiccup. Finished in classic black, the ExoMag delivers rugged reliability, smooth operation, and serious capacity—all backed by a lifetime warranty. If you’re looking to double up on rounds without doubling your reload time, this mag’s got your back.
