The RC designation identifies this rifle as the Regular Carbine configuration. It uses a full-length tubular magazine with a 6+1 capacity and two barrel bands, paired with a 20 inch barrel that balances handling and sight radius. The side-eject, solid-top receiver is the classic Marlin pattern from this era.
The steel barrel carries Marlin’s Micro-Groove rifling with the roll-mark present, chambered in .30-30. Sights include a ramped base with a dovetail-mounted front blade; the front sight hood is not present.
Furniture consists of a pistol-grip walnut stock and smooth walnut fore-end, finished with a black 'Marlin' hard buttplate. Sling swivels are fitted, and a leather sling is installed. Length of pull measures 13.5 inches.
Optics are provided by an installed Weaver 3–9x40 scope with a duplex reticle, mounted to a receiver scope base with rings. This setup offers variable magnification suitable for typical .30-30 field distances.
Manufactured in the United States in 1958, this blued steel 336 RC reflects late-1950s Marlin features, including the lack of a cross-bolt safety, while retaining the robust construction and dependable lever-action the model is known for.
