The Norinco 56S is a Chinese semi-automatic variant of the Soviet AK-47/AKM rifle, chambered in 7.62x39mm, known for its stamped receiver (in later models), hooded front sight, wooden furniture (pistol grip, handguards), and distinctive features like a bayonet lug and underfolding stock (on the 56S-1) or fixed stock, offering a durable, utilitarian design popular with civilian collectors. It was imported into the U.S. by companies like Sile before import bans and retains military-style characteristics, often marked with the Chinese Factory 66 arsenal crest.
