[Help] Can some one tell me how to do this?

Can some one tell me how i can get the l96a1 to have the animations of the artic wolf when u run with it and such? it would be most apreciated so i can finsh my l96a1 to feel like the artic wolf.

download my artic wolf mod (link in my sig) it does everything the artic wolf does, and looks almost the same as it, just a lot smaller for some reason

The only problem is that its to small cant u make it bigger
