I've been looking up pictures and threads on here all morning but haven't found and answer. I currently have a 14.5" barrel w pinned flash hider and an A2 front sight post. I have Daniel defense barrel nut for the RIS/lite rail system installed. It seems, at this point, that I may be able to install an Omega x rail 12" FSP without having to sacrifice the flashider and have another one repinned. Can you confirm?

Thanks for any help.
