This Big Boy X Model features Henry’s large-loop lever for confident cycling, even with gloved hands. The action feeds through a right-side loading gate and also allows unloading via the removable magazine tube, giving the user two clear options for managing ammunition.
The 17.4 in steel barrel is threaded 5/8x24 and capped with a knurled protector. The round-profile barrel and 1:16 twist are well-suited to the .357-38 chambering, and the transfer bar safety provides an added measure of security during carry and handling.
The rifle’s synthetic furniture is built for hard use. A pistol-grip stock with molded texturing and a rubber recoil pad provide a solid hold, while the synthetic fore-end adds M-LOK attachment points for accessory mounting. Length of pull is 14.5 in, overall length is 36.3 in, and weight is 7.3 lb for a balanced, full-size package.
Sighting is handled by a fully adjustable rear leaf paired with a ramp front. The blued steel receiver and barrel deliver a traditional look, and the H012MX model code is marked on the receiver for easy identification.
