Ultra-strong, lightweight, slide assembly replaces your shotgun’s forend with three MIL-STD 1913 Picatinny rails positioned at 3, 6, and 9 o’clock for mounting tactical lights and other accessories. Nine, removable rubber rail covers let you expose the exact parts of the rail needed for accessory attachment, while covering the rest of the rails with a comfortable, no-slip gripping surface that protects your hand when shooting and cycling rounds. Models available for Remington 870 and Mossberg 500/590.
