Państwowa Fabryka Karabinów (English: State Rifle Factory, often abbreviated FK) was a Polish arms manufacturer active between the two World Wars. Founded in 1919 as the successor to the pre-World War I Gerlach i Pulst company, Fabryka Karabinów became part of the state-owned Państwowe Wytwórnie Uzbrojenia conglomerate in 1927. It was a sister company to Łucznik Arms Factory, the Munitions Factory of Skarżysko, and several others. By the end of the 1930s, Fabryka Karabinów was one of the largest arms producers of Poland. It was destroyed during World War II.
