Deadpool does reviews for Airsoft Atlanta and here he is with the KWA MAC-11 Gas Blowback Machine Pistol... "The new KWA M-11 (M11) gas blowback airsoft sub-machine-gun features semi and full auto fire modes in a small compact package. The full auto mode has a very rapid rate of fire (20+RPS). This particular SMG fires from the open bolt position and has an impressively loud report.
