The Nordic Components MXT +9 12GA Magazine Tube (brand part no. MXT-TBS-12-9K) adds nine rounds to your existing 12-gauge magazine capacity. It is used in conjunction with a Nordic Components 12-gauge extension tube nut, which is sold separately and required for installation. The tube ships in a black finish and is part of Nordic’s MXT magazine extension lineup, built specifically to work with Nordic’s own nut and clamp hardware rather than as a universal fit. For a shotgun already fitted with the matching nut, this tube delivers the largest capacity increase in the standard MXT lineup for a fighting or competition shotgun.
