The Rifle, Anti-Tank, .55inm Boys commonly known as the “Boys Anti-tank Rifle” (or incorrectly “Boyes”), was a British anti-tank rifle in use during World War II. It was often nicknamed the “elephant gun” by its users due to its size and large bore.
There were three main versions of the Boys, an early model (Mark I) which had a circular muzzle brake and T shaped monopod, built primarily at BSA in England, a later model (Mark I*) built primarily at Jonathan Inglis in Toronto, Canada, that had a square muzzle brake and a V shaped bipod, and a third model made for airborne forces with a 30-inch (762 mm) barrel and no muzzle brake. There were also different cartridges, with a later version offering better penetration.
Although adequate against light tanks in the early part of the war, the Boys was ineffective against heavier armor and was phased out in favor of the PIAT mid-war.
