Shooting the Grizzly, the Fully 3D-Printed Rifle (VIDEO)

This is a fully 3D printed rifle ThreeD Ukulele designed. It’s called “The Grizzly” after the Canadian-built Sherman Tanks of WWII. It is a single shot .22 Long Rifle gun incorporating the coiled mainsprings of the Liberator by Defense Distributed. Like the Liberator the only metal is a 1-inch-long roofing nail.

In this first test it fired off a Winchester Dynapoint but the barrel split along both sides for about 2″ and the top of the receiver split the same amount.

Some changes will need to be made on the next design. For more, subscribe to the ThreeD Ukulele channel on YouTube.
