Black Squad Weapon Models

Hello, I was hoping if theres anyone out there who could extract me some models off a Free-To-Play game called Black Squad.
The game runs on Unreal Engine 3 but for some reason Umodel does not work when I try to extract or even preview the models im looking for.
What I am looking for is the SR-47 and the R5 assault rifles within that game. It comes in a bunch of different camo patterns but I prefer the standard camo they come in which should be black.
