I was asked the above question on a PM. was I joking on the RED DOT installation on my Ljutic, , Because it saved me $600+ by cutting down my rib by Ljutic in their price increase, which used to cost me $300 by Joe & Jimmy. I got less than $50 plus my labor, and I got my POI at 100% + anywhere I may want to change it to. Not including the Dave Berlet Adjustable Comb, which I needed anyway.
