Benelli M2 10 Shot Shotgun Magazine Extension with Picatinny Rail (10 shot total capacity)

Due to extremely high demand extension tube orders will take 4-6 weeks to complete and ship.

Magazine Extension with Picatinny Rail: This is the same sturdy Briley magazine extension made to accept a dual Picatinny rail. The fore end lock has been shortened to bring the Picatinny closer to the fore end. When using a light it will allow the switch to be as close to the receiver as necessary. The fore end is locked down, the spring is inserted in the original magazine and then the extension with the Picatinny is place over the spring and screwed onto the forend lock. Before tightening the tube to the fore end lock you orientate the Picatinny, either bottom left or bottom right. Tightening the tube to the fore end lock will also capture the Picatinny rail. Hang you favorite light or laser on it or both at the same time. Package includes magazine tube spring.

Total length measures 13 1/2 inches

Camo option available upon request for an additional $75 and 4-6 week delivery time.

Although we keep a small inventory of polished units, it may take as long as 3-4 weeks for delivery of any polished mag extension.
