The STG-44 and it's operating system.

[DarSaberclaw]

I love the gun. It is an amazing piece of german designed from the WW2.
However because of that i noticed something odd about the gun's operation.
The STG has a roller-delayed blowback system and you can see the system at work when you look at the bolt from the side.
The blowback system (bolt carrier) will grab the bolt a moment after the shot to get the next round and move back into firing position under spring tension.
The problem comes from the fact that the Bolt carrier doesn't grab the bolt.
When you cycle the gun, both the bolt carrier and the bolt move together without touching eachother. The bolt Carrier is suppose to grab the bolt and then the bolt should move back, thats where the "delayed" part comes in operation. That is the reason why it looks like a hook as well.
My question is will that kind of small detail be adressed about the specifics of gun systems and their operation? Or is it maybe a problem of the systems in place that just don't allow for that kinda small detail to be implemented yet?
I'm specifically talking about the STG-44 here because that detail is simply very visible.
Maybe im being nitpicky but at the same time i didn't know where to bring this up.

Please correct me if i am wrong, but didn't the STG44 have a Gasblowback system with a tilting lock, similar to the AK47?
I mean like yeah.... they did the delayed roller system in the MG42 and later the CETME/G§ Rifles but i was sure the STG was Gas Blowback.

So there are few ways of operation. The AK in this example is a long stroke gas operated system. It means that the Bolt carried has an extension going into the gas tube on top of the AK.
When gas goes into the system it takes the bolt with it and it has a groove in the bolt carrier that rotates the bolt at full extension unlocking it and pulls it back. That is actually the same system that the M1 Garand has.

The STG is as well a long stroke gas operated system. However its lockup is different. To unlock the bolt it actually needs to be tilted up and move out of the firing position by the hook and when the bolt carrier comes back it push it down to align with the barrel.

So yes they are both Gas blowback the difference im noticing is method of operating the main bolt itself. How it goes in and out of battery. Thats where the roller-delayed portion comes to play.
Like if you are playing the game right now. Take the STG-44 and pull the bolt back. You will see that that hook up there is not carrying the bolt out of battery. Thats the detail that i was wondered if it would get fixed or not. Instead of the entire assembly moving together.

Forgot to add you to the reply hehe. New to this. Sorry.

Yeah.... but roller delayed blowback is something else entierly, it has nothing to do with gas blowback.

Anyways, you are kinda right. It is not depicted to 100%. Its performance heavy to move the subassemblies so Anton opted out of it for some guns.

I don't simulate any of the subassemblies that move independantly

I understand.
Thank you both for the answer. I was just curiouse if that was just an oversight or a deliberet choice.
