Telescoping Open Bolt + German Space Magic

German pagan witchkraft

Literally just Newton's Third Law.

Blowback operated

>>35151605
why is the magazine so far forward?

>>35152701

Because, in order for it to function, it needs a heavy bolt and a long spring. Pretty much all SMG's from the area had that, until the UZI came along and introduced the telescoping bolt.

>Telescoping Open Bolt
Just a telescoping recoil spring assembly.

Thank you for the nonsarcastic response.

To add to it - they wanted the stock to fold under before reaching the magazine so you wouldn't have to pull it out to do it. As later similar constructions like Sterling have shown, you can have the magwell relatively close to fcg/trigger assembly, it's just that Germans wanted underfolding stock.

Just imagine trying to show hem how the g11 works

>>35152701
Germans are retarded

The bolt is a weight, and the firingpin is fixed.
When cocked (all the way back), the bolt us under tension, pulling the trigger lets it go, slamming forward to pick up a cartridge from the magazine, then immediately chambering and firing it.

Force from the discharge pushes against the boltface and shoves the bolt backwards (the bolt is the right weight to delay this happening until chamber pressures are safe), throwing it at the spring, which kind of cushions the impact, and if you haven't let go of the trigger, will immediately throw it forward once again to repeat the firing, until you let the trigger go and the sear catches the bolt the next time it comes back, or the magazine is empty.

Open-bolt blowback subguns are some of the most simplistic weapons of the 20th century, invariably the bolt will be the only moving part aside from the follower in the magazine, on many designs the firingpin is fixed to the bolt, being a monolithic part of it.

Watch someone fieldstrip an Uzi or Sten gun some time, incredibly basic. They might be amazing in their simplicity, but when someone calls the action of something magical, I'd expect it to be something really complex they're talking about, like the G11, AN94, or the M134 Minigun.

Hindsight is 20/20, I'm thinking a lot of people just initially thought "It should obviously be like a rifle for fighting", which is like half the modern idea, but the other initial idea was "Machineguns are great, but wouldn't it be great if there was a lighter variant you could run and gun with like a rifle or carbine?"
And let's be fair, even a heavy M1928 or KP/31 will be leagues easier to do CQB with than many of the early 'light machineguns', and arguably their weight makes the recoil a breeze to control, which is good for CQB.

Things like telescoping bolts or feeding through the grip wasn't considered on a wide scale.
There was a little bit of experimentation with that in late WW2 but nothing much came out of it right at that time.

It would be the Uzi that popularized those concepts.

They all had this arrangement, it was the accepted way of doing a subgun, just like the bolt-action rifle was the accepted way to make a manually repeating infantry rifle.
