The Henry H012M327 Big Boy is a full-size lever-action rifle chambered in .327 Federal Magnum, built for shooters who want a hard-hitting, handy repeater without the complexity of a semi-auto platform. This is a serious rifle for hunting medium game and controlled shooting at distance—the .327 Federal Mag delivers real stopping power in a lever gun that feels and handles like a classic, but with modern ballistics. At 37.5 inches overall with a 20-inch octagon barrel, it strikes the balance between portability and sight radius that defines the Big Boy platform.
The action is smooth and reliable lever operation; you get 10 rounds in the magazine plus one in the chamber, giving you practical capacity for hunting and range work. The blued steel receiver, barrel, and lever are finished to Henry's standards, and the American walnut stock is checkered for grip and durability. Sights are fully adjustable—a semi-buckhorn rear sight with a white diamond insert for quick target acquisition, paired with a brass bead front sight. It's a setup that works from the stand or the bench without needing to bolt on glass, though the receiver will accept optics if you want to go that route.
Weighing 7 pounds, the H012M327 won't wear you out on a day in the field, and the octagon barrel gives it that classic rifle character while adding lateral rigidity for accuracy. This is Henry's lever action for hunters and shooters who appreciate tradition and proven design, but refuse to compromise on caliber or terminal performance.

The .327 Federal Mag is suitable for medium-sized game hunting. The 20-inch barrel and lever-action platform make the H012M327 a handy repeater for hunting situations where you might need rapid follow-up shots or where brush and timber favor a shorter, maneuverable rifle.
The fully adjustable semi-buckhorn rear sight and brass bead front sight are combat-proven sighting systems that work well for hunting and general range shooting out to practical distances. Many shooters prefer iron sights for the simplicity and reliability they offer. The receiver will accept scope rings if you prefer to add optics later.
