A GrovTec hammer extension for Henry .22 and Rossi 92 rifles transforms your leverage and control when cocking, especially where scope mounting or tight geometry limits your thumb's natural range. This horizontal black steel extension bolts directly to the hammer, giving you a wider, more ergonomic contact surface—no fumbling or contorted grip needed. Whether you're running a scoped .22 or a compact lever gun, a properly fitted hammer extension turns a daily annoyance into a non-issue.

GrovTec builds these from steel with a black finish that resists corrosion and blends with most modern rifle setups. The horizontal design keeps your hand position lower and more natural than hunting for clearance around scope turrets or rings. Installation is straightforward: this extension mounts on either the right or left side of the hammer, depending on your preference and hand orientation.

One critical point: hammer extensions are rifle-specific. This model is engineered for Henry .22 and Rossi 92 firearms only. Do not install it on any other platform; doing so creates unsafe hammer function and is unsafe. If your rifle isn't on that compatibility list, GrovTec makes other extensions for other platforms—verify the model number before you buy.

If you shoot a scoped Henry .22 or Rossi 92 and find yourself fighting the hammer, this is a low-cost, legal upgrade that restores comfort and reliability to your shooting routine.
