The 24-inch fully rifled steel barrel is purpose-built for slugs, cut with a 1:35 twist to stabilize modern slug loads. The barrel is rollmarked "12 GA - 3 INCH - RIFLED," and the chamber accepts 2 3/4-inch and 3-inch 12 gauge shells. Three drilled-and-tapped holes on the barrel top ahead of the receiver provide a straightforward option for optics mounting.
Rifle-style fiber-optic sights come standard: a green fiber-optic front blade on a ramped base and an adjustable U-notch rear with orange fiber-optic elements, also on a ramped base. This setup offers a bright, high-contrast sight picture in varied lighting.
The break-action design uses an external, rebounding hammer with an interlock that prevents opening or closing the action when cocked. An automatic ejector clears the chamber decisively after firing, and Henry’s dual-direction top locking lever allows easy operation for right- or left-handed shooters. Capacity is one round.
Construction is all-steel with a matte blued finish on the receiver and barrel. The American walnut stock and fore-end are neatly checkered, with a pistol-grip wrist, sling swivel studs, and a rubber recoil pad. Length of pull is 14.0 inches, and overall length is approximately 39.5 inches. This H015-12S slug variant was introduced in November 2020 and is manufactured in the USA. The factory part number is H015-12S, and the series MSRP is listed at $636.
