Coincidentally, the day before TFB published Part 1 of a photo report on DIY weapons seized in Brazil (https://www.thefirearmblog.com/blog/2017/10/17/bunch-diy-weapons-seized-brazil-part/), news broke that the São Paulo State Civil Police had just busted a small – but very active – illegal weapons factory in the Ferraz de Vasconcellos suburb of São Paulo, the capital city. Although clandestine firearms manufacture is not something unusual in the country, this particular facility called the attention not only due to the fact that its main product, a 9x19mm stockless submachine gun, shows a somewhat decent general finish and apparent (hand-operated by agents) smooth functioning of components, but also that the type has for long (four years, at least) been found in criminal hands in different parts of Brazil.
It is also evident that that the design is broadly based on the Brazilian Mekanika Uru SMG (https://www.thefirearmblog.com/blog/2017/06/15/brazilian-9x19mm-uru-smg-reloaded/), this including the rectangular, box-like lower receiver and the tubular upper receiver. Regrettably, no pictures of the gun’s internals are available at this time, so that how much of Uru-inspired parts may be used is left to conjectures, only. Very curiously enough, the completed subguns found all has spurious “Made in Israel” markings. Some of the earlier-seized guns were “Made in Italy”… hehehe
To prove that this illegal SMG design model has been in use by criminals in Brazil for some years, here are some photos of previously seized examples:
