Our Assessment: The Browning Automatic 5, most often Auto-5 or simply A-5, is a recoil-operated semi-automatic shotgun designed by John Browning. 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”. It is also an important piece of Browning/Winchester history.

John Browning had previously sold his designs to Winchester for lump-sum payments, turning over all of the patents related to a particular model. Winchester had gotten in the habit of having their engineers and attorneys assist Browning in filing for his patents, in order to ensure that when they received those same patents they would be airtight. Browning’s experiences with Colt and FN had convinced him that he would be better off licensing his designs rather than selling them outright, but when he presented this to Winchester, they refused his terms. This ended the relationship between Winchester and Browning.

Browning would eventually license the design to FN in Europe and later to Remington for their Model 11 and to Savage Arms for their Models 720 and 755. These designs went on to be a great commercial success, the first truly successful autoloading shotgun. This Auto-5 was built by FN in 1951 with Grade I engraving on the receiver and tangs. It is chambered for 12 GA. 2 ¾” shells and has a 29 1/2″ barrel choked Full. The gun appears to have been well cared for, in Fine condition despite being more than 70 years old. This should still make for a great hunting gun for the lucky winner but would also make a great addition for collectors. Please see our photos and good luck!
