If the raised rib matters to you it seems the choice among mid range sporters is limited to the 2 of the title. Trap guns open up the choices a lot and many of them are now multi choked.Thanks for reply’s, I’m not bother about fashion I like the view on the slightly higher rib, doesn’t look as nice, the standard summit also comes with a schnabel, I prefer a beaver tail/trap style
When I was last looking to add another gun I spread the word and was able to try numerous different guns. The one I shot most was a Summit Ascent belonging to Clynt (who is a member on here) and that finally convinced me to buy a CG. I certainly wasn't aware of any difference in the sight picture with the Ascent nor did it have a more heads up mount, so I bought a standard rib Challenger because in use I couldn't honestly tell any difference other than the Ascent being slightly heavier.
