The Boss & Co Round Action Over/Under is a variation on the standard Boss O/U featuring a rounded action body that reduces width and provides a more hand-filling grip. Produced in even smaller numbers than the standard O/U, the Round Action O/U combines Boss's legendary single trigger and ejector system with the streamlined profile first applied to the SxS round-action guns. These are perhaps the rarest of all Boss current-production guns. Type: Shotgun Action: O/U Caliber: {"12 Gauge"} Capacity: 2 Year introduced: 1930, United Kingdom Weight: 82 oz Overall length: 46" Status: Active Intended use: Driven Game / Sporting
