Availability: In Stock
The GrovTec Hammer Spur Extension for Henry Big Boy 2010 & Later is a steel hammer extension built to solve a real problem: when you mount a scope on a lever-action rifle, your thumb suddenly has nowhere to go. This horizontal spur gives you a larger, more ergonomic contact surface on your hammer, restoring positive control and making the rifle genuinely shootable with optics mounted. It's a simple fix that makes a measurable difference in handling.
Made from steel and finished in black, the GrovTec extension is engineered specifically for Henry Big Boy rifles manufactured in 2010 and later. The design allows you to mount it on either the right or left side of the hammer, depending on your hand orientation and how your setup dictates. Because it's rifle-specific, fitment is straightforward—this extension is engineered to work seamlessly with your Big Boy without modification.
This is the kind of accessory that makes sense on a scoped lever gun, especially if you're running a hunting rig or reaching out beyond traditional lever-gun distances. Hunters, long-range enthusiasts, and anyone who's fought with scope clearance on a lever-action will appreciate the added leverage and control. It's not flashy, but it works.
