A new way of bypassing background checks and gun regulations could be the 3-D printer. A man has successfully printed a gun with a 3-D printer and showed the device firing.

James R. Patrick has created the needed files in order to build a gun that would come out of a 3-D printer in working order, Popular Science reports.

Patrick calls the concept the PM522 Washbear. The gun fires small .22LR bullets which are commonly used in small game hunting and by some pistols. Patrick printed his name on the gun's body.

Almost all of the gun is made of strong ABS plastic. There are three parts of the gun that use other materials including the elastic bands, a metal roofing nail that acts as the firing pin and a slab of metal. Patrick put the slab of metal on the gun just to make sure it would be detected in metal detectors.

When the trigger is puled the gun advances to the next round and readies the firing pin. The firing pin then moves forward and shoots the round.

In between shots, the firing pin rests between chambers to prevent the gun from firing if it were dropped.

Patrick's model has the option of firing either six or eight rounds.

In October 2014, a man was arrested for printing a ZigZag revolver in Japan. Others have copied the ZigZag revolver and made improvements on it.

It is very possible that people will obtain Patrick's files too and try to make improvements on the 3-D printer gun since these files can travel very easily. In some countries, simply having files to print a gun can land people in prison. In New Wales, if someone is caught with plans to build a 3-D printed gun, they could be sent to prison for up to 14 years.
