when was the first semi automatic shotgun made
Browning Auto-5 The Browning Auto-5 was the first mass-produced semi-automatic shotgun. Designed by John Browning in 1898 and patented in 1900,[4] 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 gun saw military service worldwide between World War I and the Vietnam War. A Remington Model 11 was used in the suicide of Kurt Cobain.[5]
