“The event took place this afternoon, 21/02/2018, Wednesday, around 12:50 pm, at Av. Antônio Ferreira de Jesus, Novo Horizonte district, Macapá-AP municipality. After receiving anonymous reports about a homemade weapons workshop, the team traveled to a home at the address mentioned. At the scene, the military found a 24-year-old man handling a piece of weaponry. He admitted that he made the objects. During the search they were found two homemade weapons, one similar to shotgun and another to revolver. Two ammunition of calibers 20 and 38 and notebooks with designs of firearms were also seized.“
A conventional .38spl revolver alongside an improvised 2-shot alternative. On this example the rectangular barrel is swung to the side to load and is fired by flicking closed two spring loaded strikers with the thumb. Bog simple but effective.
“Chief Superintendent Pete Henrick, commander at Birmingham East police, said: “Experts examined and test fired the handmade gun. It was found to be a viable firearm and therefore a lethal weapon in the wrong hands.”
This six shot improvised 12 gauge shotgun, which is incomplete, was seized by police along with Satan’s Plants by police in Brazil. On this crude example the drum is formed from multiple steel tubes welded together with a thumb screw below which is tightened to align and lock each chamber. The firing mechanism is missing.
