Ok thank you for your check. I have absolutely NO idea how many FPS even a ballpark drop might be. Given people say don't do more than 2 coils (risk of PME?) I thought the drop might be drastic. I'm going to start another thread since I've done a sanity check and the chrony is fine with the other AEGs semi/auto.
