Gun-Firing Drone Raises Some Eyebrows

An anonymous reader writes: A video posted on YouTube showing a drone firing a gun in a wooded area has caused some controversy today. The short video shows a four-rotored custom drone with a special rig containing a handgun. The handgun proceeds to fire four shots, handling the recoil better than might be expected. The user who posted the video also submitted it to Reddit, where a commenter noted that the apparent use of a solenoid trigger would class the device as an automatic weapon under ATF rules.
