The McGlashan BB Machine Gun is a training weapon capable of firing BBs.
During World War II, the USAAF and US Navy used thousands of MacGlashan BB machine guns to hone the skills of aerial gunnery. This much larger gun is cycled by an electric solenoid and powered by compressed air. The air pressure is higher, at 180-200 psi, but the velocity is 500 to 600 ft/s (150 to 180 m/s)
The MacGlashan Air Machine Gun company also made a McGlashan Coin Shooting Pistol for the carnival trade during the 1940s that would shoot American five cent pieces.
