It’s always fun to see people mod NERF guns into badass killing machines. Well, not killing machines exactly, with that foam ammo, but still, they can be pretty awesome. NERF’s Rival blasters fire small foam balls at speeds of up to 70 miles per hour. foam or not, that’s pretty intense. But not one to settle for the ordinary, Captain Xavier cranked things up a bit, hacking his NERF Rival into a spinning minigun fed by a 2,000-shot backpack.

You will be amazed when you see that Captain Xavier’s Rival can now shoot up to 20 foam balls every second. It does this for a over a minute and a half without needing an ammo top-off. With a gun like this, you definitely need a backpack. Ammo doesn’t last long when you are spraying foam balls like crazy.

It really is amazing to watch. The first 18 minutes of the video walk through the build details, but if you just want to get right down to the firing demo, skip ahead.

It’s completely awesome – aside from the fact that his wife is going to kill him when she gets home and finds her yard littered with little foam balls. Still, it’s totally worth it. I wish that NERF would just sell these weapons like this, without us having to mod them. I assume they don’t because they’re worried about things like child safety and lawsuits.
