One of the big no-nos in airsoft is flagging and Fox Airsoft explains why in this video... "Flagging people with your muzzle is unacceptable no matter how you cut it. The fundamental firearm safety rules apply in airsoft as well so we'd like to take a brief moment to explain what flagging is and how you can be a better ambassador of the sport of airsoft by being responsible and teaching responsibility to those around you. By keeping the sport safe, we can grow the sport!"
