The Browning wz.1928 is a Polish version of the M1918 BAR. It was a light machine gun used by the Poles in World War II.
After the Polish-Bolshevik War, in 1923 a competition was opened for a new, standard light machine gun for the Polish army that was to replace all previously used types of LMG. The competition ended without a winner and the following year the Polish ministry of war purchased 12 pieces of M1918 Browning Automatic Rifle, Lewis wz. 1923 and Hotchkiss wz. 23 each. The tests proved the superiority of the American construction, and during the 1925 competition a Belgian FN-made Browning was chosen. Although extensive tests of all the constructions were continued, the Polish army ordered a series of Belgian-made BAR machine guns, modified to better suit the Polish needs. Among the most notable modifications were the calibre (modified from .30-06 Springfield to standard Polish 7.92×57mm Mauser), the bipod's construction and mounting and the iron sights (peephole changed to v-notch type). Also, the barrel was lengthened for greater accuracy and a pistol grip was added for easier aiming. Apart from the 10,000 pieces ordered in Fabrique Nationale, Poland also bought a licence to construct the weapon at home. The first wz.28 LMGs were officially commissioned in 1927 and were officially named 7,92 mm rkm Browning wz. 1928, which is a Polish designation for 7.92 mm hand-held machine gun of Browning mark 1928.
During the German-Soviet Invasion of Poland of 1939, the rkm wz. 1928 was the standard LMG used by almost all Polish infantry and cavalry units. The German Wehrmacht captured a number of Polish-made Browning guns and used them until the end of World War II under the designation of LMG 28 (p). A number were also seized by the Red Army and used during the war.
