    This is the only M1913 spec I could find in a quick search: CLICK

    According to that image, the rail is too wide on the top surface, but not overall.

    Anyone else experience issues with either or both of these components? I just want to make sure I'm not a dumbass before I call Hahn or Bravo Company tomorrow.

    Advise is appreciated.

    I have a hard time believing that the BCM is the problem. BCM out of spec would be like finding 26 cent quarter.
