Have a Question regarding mounting an ACOG TA31F on my Rock River Entry Tactical.
What types of Rear Sights will Co-Witness? I'm assuming I can mount the ACOG directly with the Handle Off using the ACOG Flat Top Adapter, but any Rear Sights that will work?
Any HELP would be greatly appreciated! Thanks!

You cannot cowitness irons with your ACOG. That only works with unmagnified optics like Aimpoints and Eotechs. You can mount whatever rear BUIS you want (as long as it fits under the ACOG) but in order to use irons you will have ot remove the ACOG.

Thanks for the quick replies. After considerable thought, I think I'll go with: GG&G A2 BUIS (Update later with Trijicon Tritium), and the GG&G Quick Detach ACOG Mount. (GEEZ! This Stuff sure isn't Cheap!)

The Trijicon rear aperture is a waste IMO. Replace your front post with an XS tritium striped post. When you use your BUIS your eye will go right to the front post anyhow and tritium dots on the aperature will fuzz out.
