Available for these brands Benelli, Beretta, Browning, Mossberg, Remington, Winchester. The new MXT Shotgun Magazine Extensions feature a clamp groove to allow the clamp to fit more precisely on the tube and all shotgun barrels. The tube is now reversible so you can position the clamp where it best fits your shotgun or between the barrel rib lands. These feature a new end cap designed exclusively for the new MXT extension tube.

Machined from strong lightweight aircraft grade 6061 aluminum tubing, you can add anywhere from +1 to +9 rounds. Barrel nuts are designed to match OEM styling. Kit includes barrel nut, magazine tube, spring, and end-cap. We recommend using our Low-Drag Follower and our Shotgun Tube Clamp for the best performance. Our tube has an OD of 1.06″
