Henry Big Boy H012GMR .357 Mag Lever-Action Rifle with Loading Gate

The Henry Big Boy H012GMR .357 Mag lever-action rifle is a modern take on a timeless platform—compact, handy, and built to handle real hunting and sport shooting without unnecessary weight or complexity. Chambered in .357 Magnum with the ability to fire .38 Special ammunition interchangeably, this rifle pairs historic lever-action reliability with contemporary design touches like a side-loading gate that speeds reloading in the field. At 6.59 pounds and just 34 inches overall, it's a practical companion for brush hunting, backcountry work, or anyone who appreciates a rifle that handles as well as it shoots.

The 16.5-inch barrel strikes a balance between velocity and maneuverability—short enough to move through tight country, long enough to deliver the .357 Magnum's potential. The round blued steel barrel pairs with a blued steel receiver for a traditional look, while the American walnut stock feels good in your hands and ages beautifully. The large loop lever accommodates gloved hands or a quick repeat-fire grip, and the transfer bar safety keeps the rifle secure whether slung or holstered.

Sighting options let you shoot it stock or customize it to your needs. The rifle ships with a fully adjustable semi-buckhorn rear sight and brass bead front sight—a classic combo that points naturally and works in low light. The receiver is drilled and tapped for scope mounting, and it accepts the BB-RSM mount system if you want to add glass. The seven-round capacity covers most hunting scenarios, and the black rubber recoil pad absorbs what little kick a .357 generates. Swivel studs are fitted for a sling, making this rifle ready to carry all day.

Whether you're a lever-action purist, a handgun cartridge rifle devotee, or someone building a versatile truck rifle, the Henry Big Boy H012GMR delivers proven function in a package that won't wear you out during a long day afield.
