The GRS Riflestocks Mauser M18 Bottom Metal is a factory-spec performance adapter kit designed to easily convert standard synthetic-stocked rifles into premium aftermarket wood laminate setups. Purpose-built for the Mauser M18 bolt action platform, this high-strength polymer trigger guard and floorplate assembly matches the exact physical configuration required to seat the factory action into GRS Hunter Light, GRS Sporter, or GRS Thumbhole stock inlets. It eliminates the need for expensive structural gunsmith adjustments or custom bedding, providing a rigid, stress-free foundation for uniform receiver action torqueing. Complete with the crucial extended rear action installation screw, this lightweight floorplate component guarantees clean magazine indexing and exceptional shot-to-shot consistency across dynamic hunting and precision competitive target ranges.
