The Nordic Components MXT +5 Extended Magazine Tube Kit for 12 Gauge Shotguns is a drop-in mag extension kit, designed to maximize your shotgun’s total carry capacity with an additional 5 rounds of 12 gauge ammunition. This mag tube extension kit features anodized 6061 aircraft aluminum construction for superior strength and lasting corrosion resistance in a lightweight and easy-to-install package.
The MXT tubes are machined from 6000-series aluminum with a matte black anodized finish and incorporate several precision design features. A machined relief groove eliminates barrel clamp travel and ensures repeatable placement after disassembly, and the off-center location of the relief groove allows you to adjust the position of the tube without any tools. The full-length replacement spring delivers flawless feeding performance and consistent operation.
The kit ships with an extension tube, tube cap, and full-length spring. It is compatible with most 2.75″ and 3″ shells. This product requires an MXT extension tube nut to be installed on your shotgun—this tube kit will not attach without the nut. Model MXT-TBS-12-5K (UPC 816696021492) from Nordic Components.
