I bought a used 54mrs in the sporter configuration. I did not like the heavy front stage, and the light stop at the second stage. So I adjusted the first stage pull screw lighter, and the trigger weight heavier. It seems easier to manage now and really pretty nice. I did notice that there is no screw in the hole for the second stage, (right behind the trigger blade). Like I said it seems pretty good, but I was curious if the second stage screw is removed in the 5022 configuration? Did the screw fall out, or is it intentional that it is not there?

IIRC the screw BEHIND the blade is the overtravel adjustment.
