This Mare's Leg is built on Henry’s Big Boy platform, giving it the same robust 4140 steel octagon barrel and reliable transfer-bar safety system found in the full-length rifles. The 1:16 right-hand twist stabilizes a wide range of .357 Magnum and .38 Special loads, while the five-shot tubular magazine keeps the profile sleek and traditional.
The polished brass alloy receiver is drilled and tapped from the factory and comes with filler plugs installed, letting you add a BB-RSM scope base if desired. Large front-tube loading keeps the sides clean, and the oversize lever loop allows gloved-hand operation.
Walnut furniture adds to the classic aesthetic. The ramped front sight with brass bead teams with a fully adjustable semi-buckhorn rear for quick target acquisition. Made in the USA, this H006MML Mare's Leg carries the BBML serial prefix that identifies it as part of Henry’s distinctive Big Boy family.
