Fixing First Person View Animations

Hi!
I have a bit of an issue when it comes to my true first person camera animations. Basically, the rig has been animated with the character’s body in a side on sort of profile;

This leads to the first person camera looking like this;

Is there any fairly easy way of fixing this, even if it is hackish? I just want to be able to see the weapon in my hands! Thanks in advance!

P.S. The game is a multiplayer game so I can’t do anything crazy hackish ;p
