The Brazilian Uru SMG: A Study in Simplicity

[@ellomdian]

A drop safety, an auto-sear, and select fire, in a stamped steel, 7 piece subgun. That's Engineering folks. The design of the intertial drop safety alone is impressive, but the sear/trigger is crazy.

[@ragrj2009]

The trigger. I am trying to figure out how it works. I rather have an mp5 only in semi than the same gun in full auto only. This trigger is something.

Even in its extreme simplicity, this gun seems like a swiss watch compared to some things that are produced today in Brazil. Thanks Ian, for shining some light in this project. This gun seem so forgotten that it probably remains in obscurity even for brazilians. I was thinking that my father could have been issued or at least have handled one of these, since he served in the military and was a police officer right in the production time of this gun. But, after a short search, I discovered the reason for this gun's obscurity, it has a pretty hazy and infamous history. The military apparently rejected this gun some time after its adoption, for considering it unsafe and also because they wanted it to have a slower rate of fire. Seems that Olympio was an ex-military engineer and was producing this gun in a small shed under the name of "Mekanika Indústria e Comércio" in exclusivity for the military, and was hoping to get more law enforcement contracts in the future. Sadly, after the military rejected the gun, his company went in bankruptcy in 1984 and Olympio died shortly after it, in 1986. This is the part were the history gets really confusing. Apparently, the production numbers of this gun were something around 8.000, but the military only acquired 850 and the rest of the production was stored under the custody of a major gun company called Imbel. Somehow, a large number of this guns (more than 2.000) have then broke into the black market and ended up in the hands of criminals, becoming especially known for being used by bank robbers and other gang criminals. Apparently, the extremely simple project of the gun became sort of a template and inspiration for inumerous clandestine manufacturers of criminal guns since then, with the police having seized various guns and gun projects in different calibers with basis in the Uru. A pretty unfortunate story for an otherwise promising gun.

[@jasondoe2596]

João Sérgio, wow - very interesting, thank you.

[@vguyver2]

João Sérgio I had no idea about that. I suppose that is why a couple of these ended confiscated in Portugal in illegal drug shipments a decade ago. Well that was before they changed drug criminalization.

[@johnmc8785]

I wonder if the rear "drop safety" Ian highlighted in this video was a response to the military safety concerns. I also wonder if Imbel's influence was used to undermine this project. Imbel was licensed by FAN, to make an FN/FAL clone, and IIRC, Imbel was also licensed to produce a sub-gun (possibly UZI or MP5?). Imbel might not have wanted the competition. It would be interesting to know Olympio's design process, as it seems to have been influenced by guns like the "Swedish-K", the early Czech sub-guns, and perhaps the PPsh-44.

My grandfather made this gun, i never met him, but i know he was ahead of his time.Unfortunatly he died of lung cancer due to heavy smoking. If you google him you can see he was always with a cigarrete on his hands. If he was alive today, i believe he would be doing great things, not only guns. He loved nature thats why he gave this gun the name of a bird. (Uirapuru / Uru) Thank you Ian for keeping this memory of my grandfather alive. 🇧🇷

[@guilhermeradaeli2861]

As a policeman myself I only ever met one guy who claimed to have shot with one, a professor of forensics in the police academy. He was a professional marksman for decades and got his hands on one at one point of his life. He spoke very highly of it in comparison to the 40 caliber models used today. He said it felt very "smooth" and easy to control during shooting, while also being very reliable due to its simplicity of design, saying that he never got a single problem while shooting it. I remember him saying that anyone with decent knowledge of firearms could easily create an uru in a machine shop, and after seeing this video, I believe him completely. Sadly I haven't found any shooting videos of it yet.

[@KirillTheBeast]

thing is... have you ever shot an open bolt smg? You really have to be pulling on them to avoid the bolt's movement from messing up your shot. When you take into account the ergonomics, this can either be fixed by the center of mass in bursts or full auto (bolt slam makes the gun pivot downwards, recoil makes it climb) or made a lot worse. Sure, from the engineering perspective they are beautiful in their simplicity, but in terms of handling one in any caliber hotter than a pitiful 9mm I'd rather have a closed bolt german overcomplicated mess.

[@beavisbutt-headson3223]

And with the way the mag release works you also wouldn't accidently drop the mag.

[@sombraarthur]

The mag was designed to be held, because if you take a look at it, there is no fore-grip or anywhere that you can place your front hand in it... Except the mag. Where Ian held the gun in the video, would burn your hands, because that is the ventilation system of the Uru... So the mag is TO BE HELD, if you are shooting the gun.

Even so, the company that built the uru, Mekanica company failed in 1980 decade. First, the end of Brazilian military regime, in 1985, was soon followed by a terrible crisis into the military industrial complex of Brazil. Not only Mekanica closed, but also Engesa ( built tanks), Bernardini, Hidroar, etc. Even knowing that uru was simple and cheap sub machine gun, it also used an outdated magazine. The trigger was also small. Uru was crudely built. Not having a national market, from political reasons and also any real exportation possibility, the end of production of this gun was unavoidable. Yes. Uru was a cheap and reliable gun, but these facts weren't enough to avoid its failure in the market.

Man, if this had a double-feed magazine (which I don't believe would have been a very hard adaptation, though it'd have taken some more time to cook up), this would be a world-class piece of hardware.

That is a quite cool SMG mechanism!

[@ScreamingSturmovik]

wow this gun actually looks a lot like the MAT-49, speaking of which could you do another vid on the MAT-49 (preferably a standard one) and why it seems to be kind of obscure

Hey Ian, I have been wondering how often you get time to practice taking down the guns before you film. While this gun obviously doesn't need much practice, you seem to often know off the top of your head how they come apart. Is it just a mix of research before hand, and just looking at the gun? As always, great videos! Here and on Inrange!

The amount of really simple parts home manufacture is possible with a degree of quality.

[@Punisher9419]

This looks super cheap to produce. Probably one of those guns that just works.

Nice video!!! I like Brazil's guns, for exemple Imbel IA2 and CBC 12 Pump.

I worked with uru in PMPI in 2005. The security system of this weapon is very dangerous.

[@NifRR]

That's a beautiful firearm in my sight. The 9mm provides plenty of stopping power, but with little recoil. Brazilian Designers are smart. Love my country 💪

[@pricklydingus8604]

Aaaaand a gun that costs less than $100 to make, will sell for thousands of dollars because, dumb laws. 👍

It's a bitch ain't it...

[@tisFrancesfault]

FuLLeFFekT1 well that's up for interpretation.

[@bwcmakro]

"Illegal law" is an oxymoron. Illegal doesn't mean what you think it means. The government has the right to make laws that restrict things that weren't restricted before. Like cocaine, for example. That was legal for sale for a long time before that.

[@bwcmakro]

Neither are ALL guns. Or even just guns. You have the right to bear arms. It is not specified, what arms. Technically they could restrict the right to just muskets and sabres.

[@tisFrancesfault]

Doom does it include heavy artillery with nuclear shells?

Legendary Uru! Until about 20 years ago there were still many in the police of my state, today it is a museum piece. At the end of their days of operational service, many police officers no liked using it because of the various incidents involving accidental firing. If I am not mistaken there was also a 45 ACP version. Parabéns pelo vídeo!
