Briley Benelli/Breda Semi-Auto Shotgun Magazine Extension 12 Gauge

This extension allows you to increase the ammunition capacity of the shotgun. The extension is made of tough 6061 aluminum. This allows the tube to have a large wall thickness to improve rigidity without compromising overall weight. The tube screws down on the magazine and locks the fore end in place. The extension is supplied with a magazine tube spring.
