Advanced Tactical Stock System for the Mossberg 500/590, 12 gauge shotgun, utilizing a proprietary, lightweight, carbon fiber reinforced polymer impervious to weather, and able to withstand all standard gun solvents and oils. A six position, collapsible butt stock allows shot gunners of all sizes to find the optimum adjustment for fit and comfort. The military length forend can be configured with a smooth fore cap, or with a mini tri rail cap to allow the mounting of picatinny rail mount accessories without sacrificing comfort or convenience. A seven round shell holder mounts to the left side of the receiver and includes individual shell-retention adjustment for each round, without interfering with the stroke of the forend.
