The Nordic Components MXT is a shotgun magazine extension tube kit designed to increase magazine capacity on 12 gauge shotguns. This +8-round capacity option works in conjunction with the MXT extension tube nut to add rounds to your existing magazine capacity. The kit includes an extension tube, tube cap, and full-length spring.
A relief groove in the design eliminates barrel clamp travel, enabling secure and repeatable placement after disassembly. The tube features thread pitch on both ends, allowing you to reverse the tube position if needed. All capacities are measured using 2.75″ star-crimped shells; for use with 3″ or 3.5″, increase your selection by one or two rounds.
Installation requires an MXT Extension Tube Nut, which is sold separately and is necessary for proper operation. Depending on your shotgun model, installation may require modifications. The MXT represents a quality upgrade path for shooters looking to extend their magazine capacity with reliable, precision-engineered components.
