FN Browning Auto-5 Humpback Police Marked Shotgun Receiver

These are original FN manufactured Auto-5 receivers. These receivers are brand new and blued. Receivers are marked on the underside "FN" and "POL" for police. These were imported from FN by Briklee Trading Co. many years ago. As with all surplus firearms and receivers, they should be checked and assembled by a professional gunsmith.

The Browning Auto-5 was the first mass-produced semi-automatic shotgun. Designed by John Browning in 1898 and patented in 1900, it was produced continually for almost 100 years by several makers with production ending in 1998. It features a distinctive high rear end, earning it the nickname "Humpback". The top of the action goes straight back on a level with the barrel before cutting down sharply towards the buttstock. This distinctive feature makes it easy to identify A-5s from a distance. A-5s were produced in a variety of gauges, with 12 and 20 predominating; 16 gauge (not produced between 1976 and 1987) models were also available. The shotgun saw military service worldwide from World War I through the Vietnam War. The weapon was used heavily by members of the Special Air Service in the Malayan Emergency, who found the semi-automatic shotgun perfect for close quarter jungle fighting. British troops utilized the unaltered Browning Auto-5 Sporter with a 28 inch barrel, supplemented by Remington 870-R slide action shotguns with 20 inch barrels. The British found that the number of semiautomatic shotguns in a patrol were directly proportional to the number of kills made when encountering a guerilla group.
