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.

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.

Available in an array of traditional calibers to include .44 Magnum, .357 Magnum, and .45 Colt, The 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.

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.
