Hello, this item is a Zastava Yugoslavian SKS M59/66 semi-automatic rifle chambered in 7.62x39mm, measuring approximately 45 inches long. This variant is notable for its attached grenade launcher system and flip-up grenade sight, distinguishing it from earlier SKS models. Produced primarily in the 1960s–70s by Zastava in Yugoslavia, these rifles were military-issued but many were later imported into civilian markets, particularly in the U.S., where they are popular among collectors and historical firearm enthusiasts.

In excellent condition with original maple stock and intact grenade launcher setup, a Yugoslavian SKS M59/66 typically carries a market value between $600–900 USD, depending on condition, originality of parts, and matching serial numbers.
