I was in the same situation about 6 months ago. I decided to go with an Aimpoint in a LaRue mount, LaRue 7.0 rail handguard, Tangodown vertical grip, Troy back up rear sight, Knights QD swivels (rail mount up front, M4 stock mount in the rear), and a Surefire E2D in an VLTOR scout mount.
If I were you, I'd go with an Aimpoint or Eotech over the ACOG. I just sold a TA01NSN and don't regret it at all. The Aimpoint is much more versatile on an AR....just my opinion.
