A movement — and debate — was started on an international scale when Cody Wilson began creating guns using a 3D printer as part of the Defense Distributed “Wiki Weapons” project.

Defense Distributed created the first fully 3D-printed handgun called the Liberator a few months ago. Now a Canadian fellow on YouTube has revealed a 3D-printed rifle, which he continues to make improvements upon.

On the YouTube channel “ThreeD Ukulele” a man going by Matthew, who doesn’t show his face, uploaded three videos a few days ago documenting what he said are 14 total shots with the weapon before it cracks.

“I was completely confident to hand fire and will be taking it out again with a friend with a new barrel this week,” Matthew wrote to The Verge in an email.

The “Grizzly 2.0″ is a version with a 50 percent larger barrel with a “rifled bore, a larger receiver and new hammer,” according to the video description.

Here are the three videos showing the tests of The Grizzly 2.0.

One shot:

Ten shots:

Three shots:

In his first rendition of The Grizzly, Matthew explained that he named it after the Canadian-built Sherman Tanks from WWII. He wrote that he used some designs from Defense Distributed’s Liberator gun.
