Product Details


ProMag Mossberg 500-590 12 Gauge Tri-Rail Fore End w-Adapter

This heavy duty polymer forearm fits Mossberg 500-590 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. Forearm wrench included. NOTICE: The Tri-Rail Forearm is for Mossberg 500 series 12- gauge, pre-2008 production. The Tri-Rail Forearm will not fit new Mossberg 500 12-gauge shotguns with the new pinned action bar (Maverick 88 style) forearms. The Tri-Rail Forearm will not fit Maverick 88 shotguns. Use of the PM168 on post-2007 Mossberg 500, and Maverick 88, shotguns will require installation of the PM194, 7-5-8” Action Slide Tube Assembly. The Tri-Rail Forearm is only for 12-gauge shotguns
