Uncle Mike's Hammer Extension Ruger Blackhawk, H&R Topper, NEF Handi-Rifle Blue

If you run a low-mounted scope on an external-hammer rifle like a Ruger Blackhawk, H&R Topper, or NEF Handi-Rifle, you know the real problem: that hammer spur becomes impossible to reach and cock without taking your face away from the glass or fumbling blindly. The Uncle Mike's Hammer Extension solves it by giving you an extended, textured grip point right where you need it. Slip the extension over the existing hammer spur, lock it down with the included Allen screws, and suddenly you've got a proper, knuckle-friendly purchase to work the hammer—even with a scope mounted low.

This is a simple, no-gunsmith fix for a real hunting and range problem. Whether you're running a scout-style scope setup or just need better leverage on a low-sighted rifle, the knurled surface provides positive grip in gloved hands or during fast sequences. The extension mounts equally well on right or left-hand configurations, so it adapts to your dominant hand and your rifle's layout.

Blue finish matches the aesthetic of classic external-hammer rifles and stands up to field use. This is the kind of no-frills accessory that makes your gun more shootable without adding weight, bulk, or complexity.
