Thanks so much for the fast replies everyone!
I was just concerned about the front sight post getting in the way. I'm fine with the rail length as I run a KISS setup and only have a Magpul AFG2 attached to my quad rail right now. I like the way it looks with the factory FSP and would rather leave it alone instead of butcher it but I thought for sure it wouldn't work with an optic attached to the rifle because of other setups I have seen out there with flip up front sights. I guess you do learn something everyday. I will leave my Colt untouched in that aspect then. The 6720 came with a Matech rear flip up sight. Should I run that when I run an optic or is there something else I should be looking at when I take my carry handle off for use when I run the Aimpoint?
