The M1337 uses AR pattern barrels and other parts with all the mechanical hard parts held together by 3D printed parts.

The files for those 3D parts are freely given away online.

The creator sells a parts kit that has some of the parts that you don't make yourself.

And you can source the other bits yourself.

I already have all the files.

Because the gun is hand-cranked, it should fit into the exemption in current U.S.

gun laws that allows derivatives of the Gatling gun designed to avoid the NFA full auto treatment as long as they are hand-cranked.

The gun's designer, who wished to remain anonymous, was at SHOT Show next to his creation when asked why he designed it.

The answer was basically because he could.

It seemed possible because of the narrow cross-section of the AR breach and bolt, and it seemed like a cool idea at the price point.

The work from an initial idea to the first prototype took him about five to six months.

From there, refinement of the prototype took another 18 months.

It took a lot of help at this level with the different tolerances of the beta testers, 3D printers showing places where the design needed to be tweaked to be more widely useful.

The designer says the model on display at SHOT Show only had a round count of approximately 100 to 200 shots, but he has another one at home that he has put hundreds of rounds through it, and the longest string that he put through his design is an 80-round belt.

While that might not sound like much, remember this is just a normal guy who has to buy his own ammo.

Mag dumps, belt dumps, can get pretty expensive at today's prices.

He says it's hard to crank the gun quicker than 850 rounds per minute.

It's also hard to crank it slower than 650 rounds per minute.

But once you get started shooting, you tend to get into a rhythm.

At this point, the inventor of the M1337 says it's the only handheld Gatling gun on the market, just like the GI Joes had back in the 80s.
