Henry Big Boy X Model H012MX | .357 Mag/.38 Spl | Threaded

The Henry Big Boy X Model (H012MX) is a full-size lever-action rifle chambered for .357 Magnum/.38 Special with a blued, threaded round barrel and black synthetic furniture. It pairs well with a low-power variable optic such as the Vortex Crossfire II 2-7×32 (priced well under $1,000) mounted to the drilled-and-tapped receiver for improved sight picture while retaining the factory fiber-optic irons. The rifle’s combination of modern accessory interfaces and traditional lever operation suits hunting and recreational target shooting.
