GrovTec GTHM74 Hammer Extension - Post 1983 Marlin Lever Action

The GrovTec GTHM74 Hammer Extension transforms hammer operation on post-1983 Marlin lever-action rifles by providing enhanced leverage and improved grip surface. This precision-machined steel component addresses the common issue of difficult hammer manipulation, particularly when wearing gloves or in cold weather conditions.

What Makes This Different

Unlike generic hammer spurs that simply add bulk, the GTHM74 features an ergonomically contoured extension that increases leverage without interfering with scope mounting or rifle operation. The black steel construction maintains the rifle's original aesthetic while providing significantly improved functionality. Standard factory hammers often require excessive thumb pressure, especially on rifles with heavy mainsprings or when operating in adverse conditions.

Key Features

• Precision-machined black steel construction for durability and corrosion resistance
• Ergonomic contour provides secure grip surface and increased leverage
• Compatible with all post-1983 Marlin lever-action rifle models
• Low-profile design maintains clearance for scope mounting
• Checkered surface texture prevents slipping in wet or cold conditions
• Factory-style finish matches original rifle components
• Simple installation requires no permanent modifications

Field performance shows marked improvement in hammer operation speed and reliability across various shooting scenarios. Hunters benefit from faster follow-up shots and more positive hammer control during rapid target acquisition. Competition shooters gain consistent hammer manipulation under time pressure, while the enhanced grip surface proves invaluable during extended shooting sessions or when operating with gloves.
