For what you're talking about, I'd look at a Geissele rail or Daniel Defense MFR. An even easier install option would be a 12" Centurion C4, you wouldn't even have to mess with the barrel nut. The C4 rail IMO is one of the best for the money. If you'd like to get hands on a Centurion or DD MFR before making a decision let me know.
