Matt of Fox Airsoft reviews and chronos the King Arms M1A1 Thompson... "It's time for some Old School guns from back in the day of WWII. This D-Day beauty from King Arms is a 1/1 scale of the real Thompson and comes complete with a humber of sexy features. This fresh looking imitation wood that can house a large 8.4 volt battery so you can stay in the game for a long time."
