When i started with my clones i found out eventualy that the hands werent moving, they were sticking right through the rifle...after some time i came to the conclusion that i didnt envelope it to the hand bones, i looked but there was no hand bone.
after consulting psych0fred i looked on his site and came to the following conclusion...
the hand bones are HIDDEN, if you want to have proper working hands, got the explorer window, press "L" to go to the layer view. Go the bones layer, find bone_R_hand and bone_L_hand and manualy unhide then.
After you have done this you can envelop it to the hands so it will work properly.
hope this was helpfull
