Auto-5 Semi-Automatic Shotgun

The production of the Auto-5 began in 1902. Produced by F.N., John M. Browning ordered 10,000 of these shotguns in his first order. In 1999 Browning issued the "Final Tribute" version featuring engraved scens of John M. Browning, the F.N. Factory and the Browning Brothers first store. Only 1,000 of these were produced in a high-grade wood. Production of the famous "A-5" ceased after this final tribute.

To find your serial number, you will need to refer to your owner's manual. We have most owner's manuals online. You can go to those by clicking here.
