Oh, nice, you moved the goal post.
Right, you left the conversation about magazine size and now you want to talk about prototypes.
Well, I’m not having that conversation with you, stay on topic.
Magazine sizes should be correct, it’s only obviously wrong in one case, possibly wrong in one other, and practicly wrong in a third (Stinger has 200-round boxes despite purposefully that never being done, they existed but were never used).
Oh, now you decided to read the rest of my reply. 
Just poorly. 
I never said it should be semi-auto only, I quite clearly wrote “SF-Rifle”.
No idea what you’re on about mate.
There is no such thing as a WW2 era 15-round Mkb series mag, if you’ve got evidence to the contrary I ask you to present it.
I’m quite sure the Mkb 42 existed though.
You’re just putting words in my mouth about apparently wanting something I never asked for again, aren’t you…?

Alright, I’m done with you, you can’t read, and you keep making up arguments for me just to debunk them rather than actually engaging with anything I’ve written.
Absolute 10/10 dreamer. Good day.
