WW2 Weapons and others with JAM

[Chernobyl]

HE Guys.
Can you develope some weapons of ww2 with JAM-Magazines?
I thought in Russian and American Weapons, wich were still used in Nam.
And an version of the AKM, the AKMs with foltable stock and the Chicom type-56.
And can you take the weapons from Cheeky Monkey for the next version of JAM weapons and magazines and rework the old?
Because they've the disign of the originals and them of BIS look a little bit too cheap.
