Osorio Selectiva: A Nicaraguan .22 Rimfire Machine Pistol

Made by Señor Osorio in Nicaragua, this is a .22 rimfire caliber machine pistol with several clever design elements. It fires from an open bolt, using a .22-round Italian magazine of indeterminate origin. It has a selective trigger, with the top firing in full automatic (sliding rearward) and the bottom firing in semiauto only (pivoting). Aside from some sharp edges on the vz61-like folding stock, it is a remarkably well built and refined little pistol!

Stoney3K it wouldn’t be blowback if it had a tilting barrel locking mechanism

[@jimjones3867]

@@Stoney3K Well, blowback actions don't lock, so there would be no point in using a tilting barrel in a blowback action. Maybe you meant a machine gun that uses a short-recoil action (in which case, a 1911-style titling barrel lock could work). That's something I've wondered. I know there have been some machine pistols that use such a mechanism, but I don't know of any full-sized sub machine guns that do. One of the drawbacks would be that your barrel length would probably be limited to under 6 inches, and there wouldn't really be many advantages, other than some possible weight savings (from being able to use a much lighter bolt/slide than a simple blowback gun).

[@Solnoric]

I've been reading the comments and I believe I can figure out the answer to some of the questions posted there, In Nicaragua at the time there were mostly American m16 chambered in 5,56 x 45 given by the CIA, Soviet surplus kalashnikovs chambered in 7,62 by 39 as well as it's sniper variant in 7,62 X 54, and a few FALs; and for handguns both 38 short and long, 9 mm both regular and Makarov and 7,62 tokarevs. Off course ammo on those calibers were almost only in the hands of military groups and the only guns available for the public was 22 rimfire chambered weapons which were mostly bolt action rifles used for hunting iguanas (22 and 38 handguns were fairly common too), so what Mr. Osorio did was to create a tool that would take the available ammo which could be compact and with a lot of firepower, he could have also used a 38 cartridge but the recoil would probably make the gun harder to handle specially it being so short. And another thing about this guy's work, the gun might be very well done, but you would have to consider the cost of the processes needed to achieve the final result, it would probably have not been very profitable. If this comment sounds a bit hateful might be the frustration of living in a country with no army and crazy gun laws (Costa Rica), right next to a country were guns are readily available for anyone with the money to purchase it.

This is an amazing find! Quick history lession -> This was most likely a a gun created for the Nicaraguan Revolution; if it's handmade it was most likley created for Sandinista rebels (probably at the very start of the revolution) against the Auth-right Somoza Dictatorship and the Contras; BUT eventually rebels would start to gather and repair/improve the weapons taken from the Contras. The most common and famous weapons used in the revolution was actually the FAL and M1-Garand; so famous in fact that a song was written for each of them during the revolution. It's important to note that the U.S. funded the Contras to "combat communism" during the red scare which is how both sides got their hands on heavier firepower. Sandino had long since been dead but was an icon for Nicaraguan independance, especially against U.S. imperalism. So the FSLN was formed using the same/similar ideologies as other revolutionaries, not just Sandino; Pancho Villa, Zapata, Tupac (not the rapper the warrior hes named after), Farabundo Marti, and even taking notes from the French Revolution, all of which would be considered "Socialist" today; a basic principle of the goverment having very little power if any at all, and the people united controlling the country.)

I absolutely love stuff like this. The Chinese in the 30's could've really learned a thing or two from the maker of this chicken coop sweeper.

[@T_bone]

The Chinese??? Did they have a chicken coop sweeper shortage!

[@salty_armorer4027]

@@T_bone They had a civil war in where A. The wrong side won and B. Was fought with a substantial amount of shitty craft produced pistols. Ian has several videos on the Chinese mystery pistols, you should check them out, this gun blows all of them out of the water.

@@salty_armorer4027 I doubt these chinese pistols were intended for actual use, no one bothers to mill fake non functional fixed sights for that purpose.

[@salty_armorer4027]

@@antoniofdez620 why would an army waste time acquiring guns that don't work? And they weren't milled to the best of my knowledge, they were almost all done by people in the countryside with handtools that got handed a pistol and was told to make more of them.

Central and South America has... an interesting cottage industry in these sort of things.

[@borismuller86]

stereomike111 it takes a special level of crazy to just start making automatic weapons by hand. What could go wrong? Oh.

[@zackzittel7683]

Not much really... out of battery discharge? Runaway bolt? It’s a .22.... that receiver could handle a diet of outof battery discharges exclusively

a blowback smg is arguably the easiest firearm to build, especially if you don't care about single fire

[@jeffreystroman2811]

I find it very comforting there are creative and capable people all around the world. I'm sure the maker of this knows what good work it is, still nice that Ian had praise.

[@geekmansegraves]

I wonder how a scaled up version of that fire control system would work in a larger caliber machine gun. I like the design.

[@triton199]

about as big as you could go with a design like this one, practically speaking, would be 9x18 makarov

[@ScottKenny1978]

And as high as I would want to go with those ergonomics would be .32

[@Ngutovi]

Such a well thought out design. I love it.

[@DSlyde]

I watched it like 5 times, but still do not get how the semi auto works. What acts as the disconnector? If the trigger frees that block to move under spring pressure from the bolt, what stops it from going forward again when it cycles?

[@Coalzak]

It works the same way as the sear on a paint ball gun. The trigger can only interact with sear when it is moved forward - which happens when the bolt catches on it

[@disco_falcon1895]

I had the same question. After watching that section a few times, I noticed that there is a small tab on the lower right hand side of the screen that pivots up when the single shot trigger is pulled but slides straight back when the auto trigger is pulled. My guess is that this little tab is the disconnector and is pushed down by the bolt in its rearward travel.

[@deanp2012]

I'm pretty sure the little bar that pivots at the back of the trigger housing gets pushed down by the just fired bolt(which can be seen when the trigger is pulled), which then closes the locking bar which stops the sear block from being able to be pushed down. I assume if you were to hold down the semi-auto trigger, then either the trigger would be pushed forward or the bolt would close not completing its cycle causing a dry fire.

[@DSlyde]

@Mike Johnsonbaugh except it goes over that flat face when you first pull the trigger and the block moves though? It has to, otherwise it couldn't fire in the first place. It can't just be that face, as it's always there. There has to be some mechanical change after the first shot is fired to prevent the second.

[@ThZuao]

If you pull the long trigger, it lifts up a tab that seems to be what holds the sear lifted up in semi auto fire by the bolt itself. That's your disconnector. Don't @ me though.

[@peterkjellman3671]

My warmest compliments to designer. Not easy work with the available tools. Lots of thinking and knowledge behind the design. Gracias Sabio!

[@garand999]

I think the magazine is from Armi Jager AP74 .22lr !!

[@Kaboomf]

No, it's from a family of Italian (mostly Beretta) .22 carbines or rifles. Several models used basically interchangeable magazines.

This is the best handmade machine pistol ever in this channel!

[@DeanmC261993]

I’ve always been curious about a lot these obscure Latin American weapons (especially considering industry was newer there compared to other countries after the spread of it) ..kinda like a lot of their history, most people never really talk about it.. :c And yes I know there are geopolitical and cultural reasons for why certain places are more in public consciousness than others

Wow. This is really impressive, especially for something homemade. I wish more of them were made, I'd try and buy one for sure.

I need one of those, especially if I could get a 50-100 round mag.

[@crktritual]

Brigand231 In my unrefined opinion, a 50 rd would be a minimum magazine size for a .22 mag 🤔🤨🧐🤷🏻‍♂️

[@startedtech]

Lol, that'd be gigantic since it can't be double stack

[@Brigand231]

Nah, .22 isn't terribly big.

[@alpinetarn4603]

I would like to see Ian manufacture his own firearm as an inrange project. It's just be fascinating to see which mechanisms he's choose and which approaches to achieving each one of the necessary tasks.

[@Stoney3K]

I agree that it would be cool to see a feature on that, however, it may be considered as "instructional" for people who are going to home-build improvised firearms after his featured video.

[@jansenart0]

"Osorio" would roughly translate to "Bear River".

[@paulrobertson7649]

I read a book about tanks years ago, in the book there was a manufacturer from South America named Orsorio. I don't think design got picked up but the prototype was very practically made and easy for troops to use. I remember this because the name kind of sticks out and the author pointed out the practicality of the tank.

[@paulrobertson7649]

@Cghcf yes, but it's still possible that it could have been a name use for a startup company. Or not. It has been a long time. But it being a common name would not disqualified from being a company name.

[@weirdogiant6886]

I would love to see being used by some type of resistance group in a game.

[@CostaCola]

I love how simple and brutish the manufacturing is, yet how beautifully simple, rugged, and most importantly well thought out it is. I hope the internet can answer the "Who, why, when?" of this gun.

@@klausbrinck2137 .22 mag has a fair bit more pressure so you'd need a beefier spring, and in general you could need to replace the bolt as well so it has enough mass to not open too early from the cartridge going off.

@@fablesguykol3025 Thanks for the answer! but chambering for .22lr and .22mag is the same, isn´t it? So, there is modifications cause of the powder-loading, but not because of the different cartridge-dimensions?

@@klausbrinck2137 I'd need to look that part up but by in large you would need to remake some parts of the gun to handle .22 mag types of pressure and loading. As far as I know mag and LR are dimensionally the same. Edit: oh boy was I wrong. Yeah no magnum is waaayyy longer than LR. By a lot.
