It is your responsibility to confirm the dimensions of your firearm with the supplied dimensions of our part. Barrel Channel Point A: N/A Barrel Channel Point B: N/A Magazine Tube Width: 1 1/2 Magazine Tube Shoulder to Shoulder: 6 3/4 Over All Length of Part: 9 1/4 ATTENTION CUSTOMERS: On your action slide tube, measure from top of threads to bottom of collar that holds the action bars. This measurement is critical! This forend is for the 7 5/8" action slide. If your action slide measures 6 1/2", see our American Plainsman Bantam Forend Shape! NOTE: Since 2006, some newer models shotguns with synthetic forearms may not use an action slide tube at all; rather, the pump handle will have two integral bars pinned into the handle itself. If you have one of these, you cannot use a forearm that was designed to go over an action slide tube without first buying the correct length tube and action slide tube nut.
