U.S. Air Force's new survival/self-defence weapon the GAU-5A Aircrew Self Defense Weapon (ASDW).
The GAU-5A is an upgrade to the M4 carbine which allows it to be stowed in the ACES II survival kit of US Air Force fighter jets.
Much like the current M4, the GAU-5A is a shoulder fired weapon that has a semi-automatic carbine that is capable of firing a 3-round burst. It uses standard 5.56mm ammunition with an effective range beyond 200m. The weapon can be assembled/disassembled in 60 seconds without tools.
