If you run a Henry rimfire pump or lever rifle, you know that repetitive cocking can wear you out—especially during a long day at the range or in the field. The Carlson's Hammer Spur Extension for Henry Rimfire Pump & Lever Rifles is a straightforward upgrade that gives you a larger, more ergonomic surface to work with. Made from aluminum with a hard anodized black finish, this extension bolts onto your rifle's hammer spur to make cocking faster, easier, and more comfortable, whether you're right-handed or left-handed.
The knurled body keeps your thumb or hand from slipping during the cocking stroke, so you get consistent, controlled operation every time. Because it's ambidextrous, there's no guessing about fit or fumbling with your gun's orientation—it works the same for southpaws and righties. The lightweight aluminum design helps prevent uneven wear on your trigger and sear surfaces over time, which means less stress on the internal mechanics and potentially longer service life for your rifle.
Installation is straightforward, and you won't need to remove your scope or optics to mount it. Whether you're shooting with iron sights or glass, this extension works seamlessly. It's the kind of no-nonsense upgrade that makes shooting more enjoyable without adding bulk or complication to your rifle.

Absolutely. The ambidextrous design provides an easy cocking surface for right-hand and left-hand operation, so there's no need for separate left- or right-specific versions.
The lightweight aluminum extension and knurled grip help distribute cocking force more evenly across the hammer and sear surfaces, which can reduce uneven wear over time and extend the life of those internal components.
