What’s Included

- Clamp-on hammer spur extension (installed)
The 336CS features Marlin’s side-eject, solid-top receiver that is drilled and tapped, with see-through integrated ring/mount assemblies already installed (no separate bases).
Its 20 inch Micro-Groove barrel delivers excellent rifling, paired with a ramped front sight and an adjustable semi-buckhorn rear sight for clean sight alignment. Twin barrel bands secure the forearm and magazine tube in classic Marlin style.
The full-length tubular magazine offers a 6+1 capacity in .30-30, and the standard loop lever provides familiar, smooth cycling. A cross-bolt safety and external hammer round out the operating controls.
The walnut-toned hardwood stock has a pistol-grip profile with a fluted comb, white-line spacer, and a Marlin logo recoil pad. Sling swivel studs are installed. The rifle wears a uniform blued finish across the receiver and barrel, with a matching single-piece hardwood forearm.
Manufactured in 1990 and marked with the North Haven, Connecticut barrel address, this U.S.-made, full-size lever gun reflects the fit and features associated with late 20th-century Marlin production.
