SDS Imports Magazine Extension Features The SDS Imports Magazine Extension bolts onto the MAC-1014 series 12 gauge shotgun magazine tube to add usable capacity for shooters who want more rounds ready before a reload. Extending total capacity to 7 rounds gives a meaningful edge in home defense or competitive shotgun scenarios where every extra shell matters. The included spring is matched to the extension s added length ensuring reliable feeding all the way through the extended tube rather than just the factory-length section. This straightforward capacity upgrade requires no permanent modification to the shotgun s receiver or barrel. Built with an anodized Black finish this extension resists wear and corrosion from repeated handling and cycling in the field. The tube and spring are packaged together so shooters get a complete ready-to-install kit rather than having to source a spring separately. Measuring 18.30 in length the extension is sized specifically for the MAC-1014 platform and its compatible variants for a proper fit. Shotgun owners looking to stretch their MAC-1014 s capacity for tactical or competition use will find this a simple effective upgrade.
