SDS Imports Mac-2 Magazine Extension Features The SDS Arms Mac-2 Magazine Extension adds 6 additional rounds of capacity to compatible MAC-2 series shotguns a meaningful increase for shooters who rely on their shotgun for home defense or extended range sessions. Rather than requiring a completely new cap or mounting hardware the extension utilizes the shotgun s existing cap simplifying the installation process for the end user. The kit includes both the extension tube and a properly matched spring ensuring reliable feeding once the extension is installed. This straightforward design keeps the upgrade accessible to shooters who may not have extensive gunsmithing experience. Finished in a black anodized coating the extension matches the factory finish on most MAC-2 series shotguns keeping a clean uniform appearance once installed. Anodizing also adds a layer of corrosion resistance helping the extension hold up to repeated handling and storage over time. For 12 GA shotgun owners who want more capacity without replacing their entire magazine tube assembly this extension offers a direct compatible upgrade path. For shooters looking to extend their MAC-2 shotgun s round count for defensive or tactical applications this SDS Arms extension is available for sale at GrabAGun.
