The pics above are better than anything I could show, but lopping off the top half of the ghost ring does wonders for de-obstructing the dot if you don't have a perfect cheek weld. Dad loves that chopped rear (he calls it the 'Friendly Ghost'), but I have always preferred a normal ghost ring... until I got a CROM on an 870. The Haught mod is definitely a better choice for BUIS with a dot vs. a traditional GR for that reason alone.
