Some models of Benelli shotguns are being shipped with no magazine extension. Instead, these models have a cap that screws onto your magazine tube. This cap holds the barrel/forend assembly firmly against the receiver. The DMW extension nut works as a coupler, allowing you to install either a factory or DMW extension tube in place of the cap. The extension tube nut holds all components firmly in place, as the factory cap does, but adds greatly to the versatility of your weapon. Made from aircraft quality aluminum, hard anodized in matte black to match the finish of your weapon.

Length 8 1/2"
Capacity 7+1
DMW Magazine tubes are made in two peices. These include the tube and the threaded collar. Great Thought and care went into these tubes to make them the strongest available.

Step3 After proper cure time, the reciever end of the tube is wedged into a chamfer at the base of the collar. Step4 The unit is placed in a lathe and the threads are cut, insuring concentricity of the threads to tubes. Step5 The Muzzle end of the tube is rolled over to hold in the cap and spring.
