If the airsoft gun spits out the same number of BBs as fast as this box mag can feed, we don't want to be in the crosshairs of the player holding that airsoft gun. Still an interesting experiment by Bingo Airsoftworks... "This is just an experiment to modify a MAG bog mag to feed BBs at 80 RPS. The hi-torque motor is from Pololu #1163. It turns 249 RPM with a 7.4v lipo unloaded. The box mag feeds 20 rounds per revolution, so that comes out to be ~80 rounds per second, but I think it's a little less than that with the load of the BBs. This was done per a customer's request for a high ROF box mag."
