Jason Murray at Delta V Engineering has unveiled his latest project, a fully-automatic gauss energy gun. This weapon features a top section that's dedicated to housing the electromagnetic coils; "it is the carefully timed activation of these electromagnets that accelerates the steel slug along the barrel and eventually sends it flying out the muzzle." Continue reading for a video.
The ammo clip slots into the back of the gun. Each time the trigger it pressed (or held down in auto mode) a mechanical arm pushes a slug into the first coil. An infrared detector is tripped by the slug, and begins the magnetic cascade that pulls the projectile along.
In full-auto mode, the gauss gun can fire 7.7 rounds per second with a muzzle energy of 10.87J, which works out to 42.03 m/s.
