Force Animation

Can some one help me? I'm making a static space gun and I want to have the animation for the arms in the same place as where the gun is moving sach as connecting the bone handle with the hands of the player and where ever the player moves the gun the arms go along with it.. The gun is like a Mg42 with the guy right behind it standing up.. The player is in a static mode when shooting.... It's kind of hard for me to say.. Just is there anyway to force and bone in a different way so there is no need for a ton of *.dsq files for different positions?
