The William Evans O/U in 20 gauge is the lighter, more maneuverable variant of the Evans over-and-under range. Built on a dedicated 20-gauge O/U frame rather than an adapted 12-bore action, the 20-bore Evans O/U achieves a finished weight of approximately 6 pounds 4 ounces — ideal for the driven grouse moor where speed of swing on fast-crossing birds is essential. These guns are commissioned individually and typically require 18 months from order to delivery. Type: Shotgun Action: O/U Caliber: 20 Gauge Capacity: 2 Year introduced: 1970, United Kingdom Weight: 72 oz Overall length: 44.5" Status: Active Intended use: Driven Game / Upland
