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 in Japan by Miroku in 1987, after production was moved there from FN. It is a Light Twelve chambered for 12 GA. 2 ¾” shells with Grade 1 engraving and has a 26″ vent-rib barrel threaded for Invector chokes with Full, Modified and Improved Cylinder tubes included, making for quite the versatile hunting gun. Adding to its versatility is the included 24″ rifled slug barrel from Hastings which will make this gun suitable for hunting terrestrial game as well. The gun appears to have been well cared for, in Fine-Excellent condition with more signs of handling and storage than actual firing, though it has been equipped with camo synthetic Bell & Carlson stocks as well as coming with a padded sling, all set for your next hunting season.
