Here is a Possible outcome rifle. this is if Germany during the Germany-Soviet Peace time actually stayed peaceful and took a step back and realized there systems were the same socialist spectrum but on polar sides of it being Germany the FAR right and Russia the Far Left side of it. So here we are, in this scenario they worked together but move influencing American companies during the war with KGB and Nazi spy's to obtain schematics, one being the Thompson SMG that Britain was using in Africa against Germany, so with early 1943 the Prototype of the or as you newer gamers would know the STG-44 came to be, so i made a combination of the Prototypes to make this rifle here.
this weapon i will say would be strictly semi auto, well this version with the big bullets would be, normal ones would be the German 7.57 rifle rounds.
