Magazine Tube 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 placed over the spring and screwed on to the fore-end 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 your favorit light or laser on it or both at the same time. Package includes the follower and spring.

 

Total length measures 13 1/2 inches long.
