The 17.4 in carbon-steel barrel is threaded 5/8x24 and uses a 1:16 twist. Sights are high-visibility fiber-optic units: a green front on a ramp and a fully adjustable rear with two red elements.
The receiver is steel with a matte blued finish and is drilled and tapped for the BB-RSM scope base, with four plug screws installed from the factory. A transfer-bar safety is included.
The black synthetic furniture is built for utility: a pistol-grip stock with a rubber recoil pad and sling swivel studs, plus a matching synthetic fore-end featuring an M-LOK slot, a short Picatinny accessory rail, and a sling stud provision. A large-loop lever enhances gloved-hand use.
Overall length is 36.3 in and weight is 7.3 lb, keeping the Big Boy X Model compact and handy. This rifle is part of Henry’s modern X Model line introduced in 2020 and carries the manufacturer part number H012MX. Made in the USA.
