Earlier this year police in Medina Minas Gerais received a call that a man was firing firearms on a public highway. Upon arriving at the scene police encountered a 52 year old man with a shotgun and after searching his house discovered four more homemade firearms. This quad barrel favela sweeper definitely takes pride of place.
A 9mm submachine gun designed to be ultra compact and use the least number of parts possible. Nearly all components are made from square tubing including a one piece push trigger which is operated with the user’s thumb.
A quick and dirty improvised firearm assembled using pipe fittings available at any hardware store. Ammunition in this case has been improvised using nail gun charges with the crimp removed and a lead projectile inserted. The weapon functions by pulling back the ball end of the spring loaded striker bar and releasing to fire.
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.
