Ckm wz. 30 (short for ciężki karabin maszynowy wz. 30; "heavy machine gun 1930 Pattern") is a Polish-made clone of the American Browning M1917 heavy machine gun. Produced with various modifications such as greater caliber, longer barrel and adjustable sighting device, it was an improved although unlicensed copy of its predecessor, and was the standard machine gun of the Polish Army from 1931.
