The Browning Auto-5 “produced by FN”, Remington Model 11 and Savage 720 were all built on John Browning’s automatic shotgun design.
US Patent 689283 was one of his patents that covered John Browning’s auto shotgun design. This particular patent was applied for on March 18th, 1901 and granted on December 17th, 1901.
This design was the very first successful design for a semi-auto shotgun. It is really amazing to think that this design was so good that it was produced for nearly 100 years. Think about the genius required to design something so well “for the very first time in history” that it would become just second to the Remington 1100 as the top selling auto shotgun of all time. That blows my mind!!! How long did the original iPad last before it was improved with the release of the iPad 2? How long does your average vehicle get produced before it is overhauled? AMAZING. John Browning was no different than an Einstein or Newton, GENIUS!
