This 336RC is the RC Regular Carbine configuration with a 20 inch round barrel and a full-length tubular magazine for a 6+1 capacity. It uses a side-ejecting, solid-top steel receiver without a cross-bolt safety, two barrel bands, and a right-side loading gate, aligning with late-1950s production features.
The barrel employs Marlin's Micro-Groove rifling, and the bore and rifling are rated Good. This setup reflects Marlin's mid-century approach to .30-30 carbine barrels.
Sighting is traditional and practical: an adjustable semi-buckhorn rear sight pairs with a ramped bead front sight without a hood. The rifle retains its blued finish on steel components and wears uncheckered wood furniture with a pistol-grip stock. Length of pull is 13.5 inches.
Markings and identifiers include the JM barrel stamp and a P serial prefix, consistent with its 1957 manufacture in the USA. The overall configuration and features place it firmly in the 1950s era of Marlin lever guns.
