The SDS Imports MAC 1014 Magazine Extension Tube adds two rounds to the MAC-1014 semi-auto shotgun, bringing total magazine capacity to seven rounds. It's built for shooters who want more ammunition on tap without switching platforms, whether that's a home-defense setup or a duty gun. This is a direct-fit part for the MAC-1014 series and compatible variants, so it threads onto the existing magazine tube rather than replacing the whole assembly. If you run a MAC-1014 and want a straightforward capacity increase, this is the extension that gets you to a full seven rounds.
The extension threads onto the factory magazine tube, so installation doesn't require permanent modification to the gun. It carries an anodized black finish that matches most factory shotgun tubes and stands up to handling and holster wear. Overall dimensions run 5 x 0.5 x 17.25 inches and the piece weighs roughly 0.3 pounds, keeping added weight at the muzzle end minimal. The +2 capacity math is simple: a MAC-1014 that shipped with a five-round tube moves to seven with this installed. It shares the same 80041050 part number distributed across the retail channel, which is the MAC 1014 7 round mag tube configuration buyers are searching for. This same extension is often listed under the Military Armament Corporation name.
A seven-round MAC-1014 makes sense for home defense, where two extra shells before a reload can matter, and for law enforcement roles that call for more onboard capacity. Installation is a thread-on job onto the existing tube, so most owners can have it running in minutes. If you're outfitting other shotguns, we stock a range of shotgun magazine extensions from Carlson's and Lancer, and you'll find the full lineup of related parts across our magazine accessories selection. For MAC-2 owners, the matching SDS tactical extension covers that platform.
