The Henry Big Boy Side Gate .357/.38 carbine rifle is a lever-action workhorse built for hunters, sport shooters, and cowboy action competitors who want a compact, quick-handling rifle chambered in a proven handgun cartridge. This 16.5-inch barreled rifle delivers the classic Henry experience—smooth lever cycling, reliable function, and genuine craftsmanship—in a shorter package that's genuinely handy in brush or from a vehicle. Chambered in .357 Magnum with .38 Special compatibility, it swaps ammo types on the fly, giving you flexibility in the field without changing guns.
What sets this Big Boy apart is the side-loading gate—a game-changer for traditional lever-gun enthusiasts. You no longer have to open the top of the receiver to feed rounds; load straight through the side gate with the simplicity and speed that modern shooters expect. The 7-round capacity keeps things nimble while still offering enough punch for hunting or extended range sessions. The octagonal blued-steel barrel pairs with a polished hardened brass receiver for that authentic Henry look that turns heads at the range.
The rifle comes fully set up for serious use: an adjustable semi-buckhorn rear sight with diamond insert for precision, a brass bead front sight for quick target acquisition, and a drilled-and-tapped receiver ready for scope mounting via the included BB-RSM base. American walnut furniture and a brass buttplate round out the package with durability and style. At 7.76 pounds with a 14-inch length of pull, it shoulders naturally and won't tire you out on a full day afield. Transfer bar safety keeps it secure in the saddle or vehicle.
Whether you're hunting whitetail at close range, working a cowboy match, or building a serious .357 carbine battery, the Henry Big Boy Side Gate delivers lever-action reliability without compromise.
