The Grayboe HALO UMC Compatible Fixed Rifle Stock in Alpine Sponge (brand part no. HL1-UMC-ALP) is a fixed-style composite stock built for shooters who want a durable, hunting-ready replacement for a factory wood or basic synthetic stock. Grayboe molds the HALO line from a reinforced composite material rather than injection-molded plastic, giving it more rigidity and better bedding consistency than typical factory stocks while staying lighter than a full aluminum chassis. The Alpine Sponge finish gives it a distinctive mottled colorway that stands out from standard black or camo stock options. It’s built to accept UMC-compatible bottom metal and hardware for a clean drop-in installation.
