I have even gotten Loadout Pro III so I can walk faster with the damn thing.
However the glitch is happening when I pick up a HMG that has already been ripped off the stand.
Basically the crosshair won't zoom in fully as it will when I have ripped it off the stand myself.
This make it so inacurate it's basically a glorified shotgun as the spread is too massive to be used at any kind of range.
If you have seen this problem plead contribute
