content: Pretty sure the gun is a .22 magnum, kel-tech. The description for the video also mentions that: "The length from the muzzle to the rear of the frame is over 26." That thing is gonna be fighting the air so hard, you'd hear it well before a .22 would be in range. Still, the implications are scary if you like owning drones of any kind. This wont end well for enthusiasts, legally speaking.
