Discovered by Drug and Firearm Squad detectives on June 3, the 4kg gun can fire 15 lethal 9mm rounds with just one pull of the trigger.

Built using plastic and other materials, the gun allegedly took only two days to make and costing about $40.

According to police when they seized the weapon from the Slade Street residence, they also found a 3D printer, five gel blasters, a silencer and ammunition.

The young man, who does not hold a firearms license, has been charged with several offences including the unlicensed manufacture of firearms or ammunition and possession of a prohibited weapon.

Detective Senior Sergeant Blair Smith said the discovery of the assault rifle was "deeply concerning".

"Although it resembles a toy it has the ability to cause serious harm within our community," he told reporters on Monday. 

"It's deeply concerning that this man was able to manufacture this firearm at home with a 3D printer and readily available materials

"These types of firearms are unregulated, unlicensed and have no place within our community," Sgt Smith said.

The home-made weapon is of the same calibre as those used by WA police.

The teenager will front the Perth Magistrates Court on June 22.
