The FNC (Fabrique Nationale Carabine) was FN’s followup to the unsuccessful CAL rifle. Chambered for the newly-adopted 5.56mm NATO cartridge, the FNC uses a long stroke gas piston system very reminiscent of the AK, combined with a stamped upper and milled aluminum lower. After about 5 years of development, the FNC was put on the market in 1980, and was quickly purchased by Indonesia, along with a license for domestic production as the Pindad SS-1. It would also be adopted by Sweden as the AK-5 (minus the 3-round burst functionality) and Belgium. About 6,000 semiautomatic sporting models were imported into the US. A number of those, including this one, were legally registered as transferrable machine guns before 1986.
