William Evans introduced the over-and-under shotgun to their range in the mid-20th century in response to the growing preference for the single sighting plane among driven-game and clay-shooting clients. The William Evans O/U in 12 gauge uses a sidelock action built to the same standard as the SxS, with selective ejectors, a Boss-pattern single trigger, and chopper-lump barrels regulated to the client's ammunition specification. Production is limited and demand is strong. Type: Shotgun Action: O/U Caliber: 12 Gauge Capacity: 2 Year introduced: 1960, United Kingdom Weight: 82 oz Overall length: 46.5" Status: Active Intended use: Driven Game / Sporting
