The Grayboe Flagstaff Fixed Rifle Stock in Alpine Sponge (brand part no. FS1-UMC-ALP) is a fixed-style composite stock built to fit UMC-compatible rifle actions. Grayboe stocks are known for a fiberglass-reinforced composite layup that adds rigidity and weather resistance over a traditional wood or basic polymer stock while keeping weight manageable for hunting and field use. The Alpine Sponge finish gives it a distinct mottled camo-style look that stands out from a plain black stock. It is a solid upgrade for hunters who want a tougher, better-looking stock on a budget-friendly action.
