Don’t let the vintage aesthetics fool you these pistol-caliber lever guns are designed for the modern enthusiast.
In the past we’ve taken design cues from the original 1860 Henry Repeater opting to utilize a removable tube magazine. Now the Big Boy’s polished brass receiver sports a side loading gate allowing you to top off the tube magazine without dropping the rifle from your shoulder. We’ve also retained the traditional magazine tube for safe and easy unloading. With both loading options at your disposal you’ll always have your rifle at the ready.
Classic pistol cartridges see considerable performance improvements when fired from the Big Boy’s 20” blued steel octagonal barrel making these rifles a versatile tool to Protect and Provide. In addition a fully adjustable semi-buckhorn rear sight with a reversible white diamond insert paired with a brass beaded front sight makes target acquisition effortless.
True to Henry form these rifles are constructed with exquisite attention to detail using fine American-made components. Both the straight-grip stock and forearm are crafted of select American walnut accented with a polished brass barrel band and Henry’s signature polished hardened brass receiver. All have the smooth action and crisp trigger that distinguishes an authentic American-made Henry.
For those looking to experience an undisputed piece of Americana whether it’s at the range in the field or on a cowboy action stage the Big Boy Brass Side Gate is guaranteed to bring out the West in you.
