The Color Case Hardened Side Gate variant combines a hardened steel receiver with a blued 20 inch octagon barrel for a traditional, durable configuration. The color case hardening provides a distinctive finish on the steel receiver, while the barrel maintains the classic Henry octagonal profile.
This rifle is factory chambered in .357-38 and uses a 10-round tubular magazine with a 10+1 maximum capacity. It offers a dual-loading system that accepts cartridges through the side loading gate or by removing the inner brass tube.
The sighting system is iron sights configured with a ramp front brass bead and an installed Skinner EXPRESS receiver-mounted rear sight. This setup delivers a sight picture aligned for quick acquisition with the brass-bead front.
Furniture is American walnut with a straight-grip, checkered stock and matching forend. A black rubber buttpad, sling swivel studs, and a 14 inch length of pull support practical field use. The rifle uses a lever-action mechanism with a transfer-bar safety and a 1:16 twist rate.
Made in the USA, this Big Boy (MPN H012GMCC) blends classic lines with useful upgrades. The steel construction, color case hardened and blued finishes, and receiver-mounted rear sight make this a well-specified example of Henry's side-gate design.
