Would this require a license?

While it may only be able to shoot a few cans right now, we certainly wouldn’t want to be in front of [Jason]‘s fully automatic Gauss gun capable of firing 15 steel bolts from its magazine in less than two seconds.

The bolts are fired from the gun with a linear motor. [Jason] is using eight coils along the length of his barrel, each one controlled by an IGBT. These are powered by two 22 Volt 3600mAh LiPo battery packs.

As for the mechanical portion of the build, the bolts fired from this gun are actually 6.5mm nails, cut off and sharpened. These are chambered from a spring-loaded magazine, with each new bolt put into the breech with a small solenoid retracting for an instant. The frame is constructed from a square aluminum tube with additional pieces cut with a hacksaw and bent with an impromptu bench vise brake. If ever there was a person deserving of a bench top shear/brake, [Jason] is the man.

The muzzle velocity of these bolts is about 40 m/s, with a muzzle energy that’s about 3% of a .22 LR round. Not deadly, but more than enough for picking off a few cans and bottles in a garage. You can see the video of this futuristic Gauss machine gun belo

I believe in second chances… it’s called reloading

depends on which sports cartorgary its comes under, shooting or archery. if archery then no license needed. either way the man in white will need a change of underwear when he sees this in your suitcase.

if you say it can not be done, then you are right, for you, it can not be done.

Sorry didn't have the 'sound' on when watching the video clip - so my question is...
1. What is the source of energy that propels the darts?
2. Does the weapon produce any sound?
It seems quite lethal at short distances & looks mean too!!!!

1). battery pack.. and the form of energy that propels the darts is electromagnetism.
2). yes, it does, but the sound is kind of mechanical and not an explosion sound.
