You've obviously never seen pics of MD's setup, or Dirtfarmer's either which is similar. If you have you'd immediately understand that these setups in now way, fashion, or form impact POI. Also, changing the MS to another rifle with a different contour takes a whole 30 seconds maybe, and you don't have to dicker with the pads every time if it's set up right. I can count the missed readings from the MS over 3 years on one hand.
