Henry Big Boy X Model .357 Mag / .38 SPL Rifle 17.5" Threaded Barrel - 5/8x24

The Henry Big Boy X Model redefines what a modern lever-action rifle can be. Combining classic American lever-gun heritage with tactical versatility and modern performance upgrades, this rugged platform is built to handle everything from hunting and home defense to truck-gun duty and range-day fun.

Designed for shooters who demand adaptability, the Big Boy X Model features durable black synthetic furniture with integrated M-Lok and Picatinny mounting points, giving you the freedom to customize your rifle with lights, slings, optics, and accessories. The threaded 17.4" barrel is suppressor-ready right out of the box, while bright fiber optic sights ensure rapid target acquisition in low-light or fast-moving situations.

Built around Henry’s trusted lever-action system, the rifle retains the traditional removable tube magazine while adding a side loading gate for fast top-offs without removing the tube or muzzle device. Chambered in versatile .357 Magnum and compatible with softer-shooting .38 Special ammunition, the Big Boy X Model balances power, controllability, and practical utility in one highly capable platform.
