Carlson's Hammer Spur Extension Henry Big Boy Post 2010 Aluminum Black

The Carlson's Hammer Spur Extension for Henry Big Boy (Post 2010) is a thoughtfully designed upgrade for lever-action shooters who want faster, more confident cocking without sacrificing balance or reliability. If you run a Henry Big Boy and find yourself fighting the hammer spur on long days at the range or in the field, this aluminum extension gives you the leverage and control you need—whether you're right-handed, left-handed, or switching between the two.

Built from aluminum with a hard-anodized black finish, the extension is lightweight enough that it won't throw off your rifle's natural handling or create uneven wear on trigger and sear surfaces. The knurled body keeps your thumb locked in place during the cocking stroke, eliminating the slip and fumble that comes with a standard spur. Installation is straightforward—no gunsmithing required—and the design works seamlessly whether you're running iron sights or have a scope mounted on your Big Boy.

This is the kind of upgrade that pays dividends the moment you cycle the action. For hunters working through thick brush, competitive shooters drilling repetition, or anyone who values smooth, ambidextrous operation, the Carlson's extension transforms the Big Boy's manual of arms from a chore into second nature.
