what he said. think of it like this: put your gun down on a table or something so that "Tippmann 98 Custom" is facing up, loosen all the bolts, and take off the left reciever half. then put the safety in under the trigger in its appropriate slot, so that the red o-ring is pointing up. then put the reciever back on, and tighten your bolts.
