You must have messed something up inside to cause it to shoot funny. Do you have any more left over parts?
no that's the only part other than a small circular piece that poped out which covered the motor in the hand grip. i re installed that correctly but i think i may have to open it up again and see what happened...i'll send picutres if i find anything.
