Illegal SMG factory busted in São Paulo, Brazil

    Coincidentally, the day before TFB published Part 1 of a photo report on DIY weapons seized in Brazil (, 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.

    The partially-completed specimen on top of photo still has the trigger and magazine release lever missing, while the one below sports transversal openings in the forward end of lower receiver. Ventilation orifices in the tubular receiver are reminiscent of those found in the Uru.

    It is also evident that that the design is broadly based on the Brazilian Mekanika Uru SMG (, 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

    This “ready-to-go” weapon being manipulated by a police agent shows that, unlike the Uru, the magazine catch is pressed forward to actuate. No signs of applied safety or fire selector are evident.

    The spurious “Made in Israel” markings on the left side of this receiver are followed by an equally bogus “31568UH” serial number.

    I wonder if the five-point stars engraved on some of the subguns had the intention of appearing “Israeli”, but, you know, the Star of David is a six-point design… The small-diameter spring seen on table is probably for the recoil action (like the Uru’s), the larger one being for the 30-round magazines.

    A whole bunch of magazines lying on a table show their stamping manufacture process.

    Discernible in the middle of gun components are an eight-round revolver cylinder and a six-round 12-ga cylinder. A revolver shotgun in the works?

    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:
