The clamp is a lightweight, aluminum assembly designed to lock the barrel and extended magazine tube together securely, also serving as a mount for tactical lights or other accessories.
It includes left and right-side sling swivel sockets for pushbutton swivels and a 2" Picatinny rail that can be attached at 3 or 9 o'clock positions.
Compatible with 12 gauge Remington 870, 1100, 11-87, and Benelli M1, M2, M4, M1014 shotguns, the clamp and rail are made from 6061 T6 aluminum with a matte black finish.
