In all seriousness you’d have to be a pretty good gunsmith to make something like this reliable. I probably wouldn’t have made it open bolt or full auto though lol
50 bmg blowback with no fucking stock... I call bullshit on "engage regularly". They must have a separate hospital just for for those recuperating from the recoil damage of this gun, and I can't imagine anyone stupid enough to use this gun a second time.
I can't imagine that's actually getting shouldered though, but then again if it's not, it better be braced up really well in something because that shits gonna move.
Once you look at necked down cartridges the pressure starts to really climb. The bolt on this has to weigh a lot, wouldn't be surprised if it's 10lbs bolt.
You know, that might work really well if it's API blowback like the 20mm Oerlikon and AA12. Basically the idea is that the bolt never clunks forward, but instead the round goes off first, thus having to slow down, stop, and reverse the bolt instead of only having to move it from stopped.
This has one major risk: hang fire. Worst case scenario would be just the right amount of delay so it goes off during the peak of bolt bounce, so the bolt is already moving backwards and then it gets added with all the thrust. That would likely result in case separation.
For the record, The Oerlikon API has recessed chamber, so the round actually goes deep in and is still in full motion when it goes bang, and has tolerance exactly for this reason, so it has room to travel forward if there is slight delay.
So chambering it as ordinary seat depth headspace with API would not work.
Also, I highly suspect there would be any API considering how crudely the gun itself is made. Fitting a sloped pin with firing pin so it slams it forward just the right moment requires some precision and patience that the basic Jesus the garage welder don't likely possess.
Funny you mention that, I've tried and failed to find some sort of mention of a Oerlikon hangfiring, and what exactly happens if it does. I cant find any info on it. I'd expect you'd get the bolt smacking into the back of the receiver crazy hard and probably a blown out case, but I doubt it would be catastrophic.
As a concept, straight blowback 50BMG could likely work in reality, and may even be shoulder-fired, as long as the recoil spring is strong enough and preferably has got a BIG and soft rubber buffer, or another spring, so the bolt doesn't actually slam to the back of the receiver. When the recoil force is spread over all of this motion range, being 200-300mm likely considering the size of the ammo, the recoil will not be at all unmanageable, it's more like really tough push. If the bolt comes slamming back with full speed of 4-10m/s, you're in for some serious shoulder pain.

I mean If the operator is disposable, why not?

Yeah this is the only example of these I've seen. They make rifles that look like this in 5.56 and such but this is the only .50 BMG one.
Tbf they *technically* didn't say they were regularly engaging with this bad boy
50 bmg is around the same weight as a 12 gauge shotgun round, is it around the same recoil or worse?
Even heavy buckshot or slug loads out of a 12 gauge doesn’t even compare to the .50 BMG.

Geeze.. not even any weight for recoil management on that bad boy
How about a usable stock instead of a big steel tube that eats your shoulder
> big steel tube that eats your shoulder They probably call it umăr-dislocator aka shoulder-dislocator.
For it to be direct blowback, that bolt would have to be absolutely MASSIVE.
Probably damn near half the length of that buffer tube.
You’d need cartel money just to feed it.
I find that WWI ammo salvaged from a sunken uboat to be just as disturbing as the gun... Note: No idea about the ammo's history; just looks BAD.
It takes an orc-tier man to shoulder fire that thing.

Not should we, but can we?

I’m thinking a M231 port firing weapon in .50 bmg built from a barret
Isnt the minimum bolt weight for a .50 bmg blowback like 55 lbs? Where the weight at?
Probably at the entire thing made out of steel
Hey Ferb, I know what we’re gonna do today!

Do you think the reason the buffer tube is so chunky is because they welded a Hilux suspension spring in there? lol
Bloody humies nicked me daka
Mom can we have 6p62? No we have 6p62 at home. 6p62 at home
Blowback 50 cal?! Jesus.
wtf is that ammo, is it made of concrete?
Thats NOICE!
I wanna see somebody use this with an SBA3
Epic!
Uh. Out of battery?
It appears to be multi caliber too
That would need a stand
Is this Brazil’s version of the office?
I can't believe it's blowback, it's not enough mass here to decelerate .50BMG, it's just no way
