The rkm wz. 28 or Browning wz. 28 is a Polish derivative of the M1918 Browning Automatic Rifle. It was used as a light machine gun by the Polish Military and Polish Resistance forces during World War II.
Chosen after a competition between similar weapons, the BAR design was modified by FN Herstal to meet Polish requirements and then licence-produced by the Państwowa Fabryka Karabinów.
