Integrated Ejector Design
The ExoMag features an integrated ejector built into the magazine body. This design allows the magazine to function in standard AR-15 lower receivers without requiring modification or dedicated 9mm lower receivers. The integrated ejector eliminates the need for specialized lower receivers, simplifying caliber conversion and reducing overall build costs.
40 Round High Capacity
The 40 round capacity provides extended shooting sessions between reloads, particularly valuable in competition and training scenarios. This capacity works with all 9mm Luger ammunition types including hollow points, full metal jacket, and specialty loads. The polymer follower ensures consistent feeding through the full capacity range.
Last Round Bolt Hold Open
The last round bolt hold open feature locks the bolt carrier group back after the final round is fired. This provides a clear visual and tactile indication that the magazine is empty. The feature speeds reloads by eliminating the need to manually lock the bolt back during magazine changes, particularly important in timed competition scenarios.
Standard AR-15 Lower Compatibility
The ExoMag works with standard AR-15 lower receivers when paired with a 9mm upper and blowback bolt carrier group. This compatibility allows shooters to convert existing AR-15 platforms to 9mm without purchasing dedicated 9mm lowers. The magazine fits standard AR-15 magazine wells and uses standard magazine release mechanisms.
Three Pack Value
The 3 pack quantity provides multiple magazines for competition stages, training drills, or range sessions. Having multiple magazines loaded reduces downtime and allows focus on shooting fundamentals rather than constant reloading. Lightweight polymer construction makes carrying multiple loaded magazines manageable.
Follow safe handling and manufacturer instructions. Verify compatibility with your specific 9mm upper and blowback BCG. Ensure compliance with all applicable laws including magazine capacity restrictions in your jurisdiction.
