[@MemeMagicDotWin]

@@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).

I think you missed describing how it actually functions for semi-auto fire. By your description of the system it would fire full auto no matter which part of the trigger is used. I assume the part that rises when the semi-auto trigger is pressed is a disconnector, but can't tell for sure.

[@justthetip7136]

Love these early uploads, they go great with my coffee before my shift starts. Keep it up Ian!

[@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.

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.

It's really amazing the quantity and quality of absolutely uniquely weapons exist out there. I very much appreciate your bringing them to our attention Ian.

[@accused918]

Looks like something straight out of the Fallout universe

[@julianjohnson7908]

Berzerker reminds me of the 9mm in Fallout 4!

[@Salesman9001]

I wish they'd used models like this instead of silly pipeguns.

[@singami465]

I wish Bethesda took inspiration from this, rather than making absolutely ridiculous quasi-steampunk designs. Shitty weapons in Fallout is what pains me the most.

[@sofielee4122]

somebody should mod it in tbh

[@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.

[@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.

[@jasperlawrence5361]

What a fantastic gun, really good and clever, by far the best handmade weapon I have seen on Forgotten Weapons, bravo Osorio!

[@toolthoughts]

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

[@toolthoughts]

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

[@Tim-Kaa]

I can recognize an amazing amount of skills and efforts that went into building this gun. Great job.

[@FrostyFoxDrake]

Osorio: *sees MAC 10 stock* O: ... O: “I’m gonna make this even worse.”

[@Pommezul]

"You can't make it worse" Osorio: Hold my toña.

[@Gameprojordan]

it's more like a scorpion stock, mac 10 stock is collapsible like an mp5 stock

[@brianreddeman951]

Awesome series of automatic weapons. Big thank you for letting Ian cover these weapons.

[@TheVgrey]

Would like to see a refined version of this

[@vanboy5697]

I thought it would be some prototype weapon to be sold to the army of Nicaragua. Impressive craftmanship.

[@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

[@georgewood9482]

Incredibly well engineered!

[@2Potates]

Wonder what the rate of fire on this thing is.

[@jamestheotherone742]

The whole mag. lol.

[@ScottKenny1978]

Probably pretty high, that doesn't look like a very heavy bolt.

[@TurtleButter]

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

[@Brigand231]

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.

[@putridtortilla6285]

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.) Again, this is an amazing find, keep up the good work!

[@weirdogiant6886]

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

[@richardlee754]

That is super creative and rad.

[@Redbird1504]

I need this in 22 Mag

[@pastorofmuppets325]

22 Mag is a helluva round (for it's size)! 😜

[@klausbrinck2137]

If it is good for .22, shouldn´t it be as good for .22 mag too??? I don´t get it, please explain!!!

[@fablesguykol3025]

@@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.

[@klausbrinck2137]

@@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?

[@fablesguykol3025]

@@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.

[@Doitallgp]

I saw the thumbnail and thought “what could possibly go wrong?” But I’m actually really impressed

[@jansenart0]

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

[@seanbordenkircher7854]

This is one of the more video-gamey weapons that you've gotten your hands on Ian, I love how Red Faction this looks.

[@Stynze]

chances are it was actually made by a 'red faction'

[@drummaghua2687]

Imagine making it by 3d printing. I just found some scifi feeling on it.

[@atomic_wait]

This thing seems really slick and well-considered! Assuming it actually functions this is a really impressive piece of work for a private one-off. Good job, Osorio!

[@Kukus-xy3gi]

Last time i was this early, rhodesia was still a country

[@rob9472]

That really is a spectacularly designed little gun especially considering it was hand made, Also I think its quite an attractive looking firearm.

[@premzyy1791]

the virgin Luty vs the chad Osorio

[@neurotoksyn]

Whoever Osario was, he had some talent that's for sure. With a little refining and upping the machining standards, this would be a remarkable little subgun. Especially remarkable considering it's a one off homebuild.
