The ProMag AA500SC is a sophisticated Tactical Stock System made specifically for the Mossberg 500/590, 12 gauge shotgun. Crafted from a proprietary carbon-fiber reinforced polymer, it ensures lightweight handling while offering exceptional weather resistance and compatibility with all standard gun solvents and oils.
This advanced system features a six-position, collapsible butt-stock, facilitating optimum fit and comfort for users of all sizes. For added convenience, there's a 7-round shell holder which securely mounts to the left side of the receiver. It also incorporates individual shell-retention adjustment for each round, without obstructing the stroke of the forend.
