The ProMag Tri-Rail heavy duty polymer forearm fits Winchester 1300/Speed Pump 12-gauge pump shotguns. The forearm has three sturdy Picatinny rails located at the bottom, left and right hand sides. These rails allow attachment of flashlights, lasers, vertical grips and other accessories directly to the shotgun. This eliminates the need of remote corded switches, barrel clamps and clutter. No modification is required, uses factory hardware. Forearm wrench included.
