The Royal Air Force adopted this design and had it manufactured by Vickers Armstrong and BSA to fire the .303 round. It was named the Browning .303 Mk II in British Service. The Browning .303 is essentially the 1930 Pattern belt-fed Colt-Browning machine gun with a few minor modifications for British use, such as firing from an open bolt. This prohibits their use for gun synchronization through a spinning propeller. The Browning was designed to fire hydraulically as a wing-mounted machine gun but was also adopted as hand-fired mount for use in bombers and reconnaissance aircraft. The Browning .303 had a rate of fire of 1150 rounds per minute. It was used on the RAF's "eight-gun fighters" such as the Hawker Hurricane and Supermarine Spitfire, and as a turret gun in the Boulton Paul Defiant, Handley Page Halifax, Short Stirling, Avro Manchester, and Avro Lancaster bombers, and the Short Sunderland flying boat installed in various Boulton Paul or Nash & Thomson turrets. For hand-held moveable mount use the Vickers K gun is preferred.
