I took the trigger out of my son's Apex and put some moly on the mating surfaces. It wasn't that hard actually, the only thing you need to watch out for is the trigger spring, it could come out if you move the trigger wrong. It seems to have helped some. Your other option is to send it in to BPI and let them do it, I think they may do it for the cost of shipping, you would just lose the time it takes to get it done.
