John Browning's first semi-automatic shotgun and arguably the most historically important shotgun ever made. The long-recoil operating system Browning patented in 1900 became the basis for virtually all long-recoil semi-automatic shotguns that followed. Manufactured by FN Herstal in Belgium (1902-1975) and later in Japan by Miroku for Browning Arms. Also licensed to Remington (Model 11), Savage (Model 720), and others. In continuous production in some form for nearly a century. The modern Browning A5 reintroduction (2012) uses an inertia system and is mechanically unrelated. Original production ran until 1998. Type: Shotgun Action: Semi-Automatic Caliber: 20 gauge Capacity: 5 Year introduced: 1958, Belgium Weight: 131.2 oz Overall length: 49.5" Status: Discontinued Intended use: hunting, collector, historical, competition
