When the riflemaker, known only as Matthew, first fired the .22-caliber rifle, the gun cracked after the first shot. Now, the rifle, known as the Grizzly, is back and better than ever, according to Matthew, who furnished the rifle with a thicker barrel.
Matthew managed to fire 14 shots before the plastic around the barrel cracked. When first testing the rifle, Matthew used a string to pull the trigger from a distance. Now, he seems confident enough to pull the trigger by hand.
To reload the gun, Matthew has to pull the barrel off and use a stick to dislodge the spent shell casing, then load another round and reassemble the rifle.
3D-printed guns have inspired increased debate on the availability of blueprints for such weapons. Cody Wilson, creator of the Liberator, posted the gun's blueprints online for anyone to access. Although the plans were taken down at the request of the US government, they remain widely available on file-sharing networks. Since then, improvements and tweaks have been made to those blueprints.
Defence Distributed, Wilson's non-profit organisation, claims to have the plans for the lower receiver of an AR-15 semi-automatic rifle, the portion of the civilian rifle that's classified as a weapon.
