Feb. 19 (UPI) -- The Air Force announced Wednesday that the Gunsmith Shop has completed delivery of a new rifle -- known as the Air Crew Self Defense Weapon, or GAU-5A -- for aircrews in most ejection seat aircraft.
The 7-pound, 5.56 mm caliber rifle is based on the M4 carbine and designed to provide a downed aircrew with additional firepower while they wait for rescue, the Air Force said.
