A GrovTec hammer spur extension for Marlin lever action rifles (1957-1982) transforms your shooting experience by adding a larger, more accessible contact surface to your rifle's hammer. If you run a scoped setup on your Marlin or simply want better control and faster cocking in the field, this steel extension solves the clearance and grip issues that plague hunters and shooters with vintage lever actions. The extension mounts directly to your existing hammer and can be positioned on either the right or left side, depending on your shooting hand and scope configuration.
GrovTec builds these extensions to last, using quality steel and a durable black finish that resists corrosion and matches your rifle's aesthetic. The design is specific to Marlin lever actions from the 1957–1982 era, so you know it'll fit and function without modification. For anyone running glass on a classic Marlin or dealing with a cramped hammer spur in a hunting situation, this is a practical upgrade that makes a real difference in handling and speed.
Installation is straightforward, and the extension works with your rifle's factory trigger group—no guessing or gunsmithing required. Whether you're a lever-action purist looking to modernize your optic setup or a hunter who wants faster, more reliable hammer manipulation in cold weather or gloved conditions, this is a solid choice.
