I don't believe any of the accutrigger models have an overtravel screw. A good check for sear interference with the trigger is to hold the trigger down and operate the bolt release through its full stroke. It should not "rub" the trigger behind the trigger sear. If it does something is preventing the trigger from moving back far enough. This is common where overtravel screws are used as in aftermarket triggers & the old three screw triggers.
