SDS Imports Magazine Extension Features The SDS Imports Magazine Extension for MAC-2 is designed specifically to fit Military Armament Corporation MAC-2 series shotguns and compatible variants adding two rounds of 12 gauge capacity to the magazine tube. The extension utilizes the existing cap already present on MAC-2 shotguns which keeps the installation process simple and avoids the need for additional hardware purchases. Both the extension tube and the matching spring are included in the package giving owners everything needed to complete the upgrade. This added capacity gives shooters more rounds on tap before a reload is required. The extension is finished in an anodized black coating matching the factory finish found on most MAC-2 series shotguns for a clean consistent appearance. Anodizing also adds a layer of corrosion resistance helping the extension hold up to repeated handling and field use. Because it is purpose-built for the MAC-2 platform fitment is straightforward without modification to the host firearm. For MAC-2 owners looking to extend their shotgun s round count for home defense or tactical applications this magazine extension offers a direct no-fuss solution.
