I bet they'll be in the acog price range on the street.
I think that the real question here is fixed magnification vs variable magnification. If I am reading that wrong, I apologize.
Personally I would go with a lesser quality optic with variable magnification. The ACOG is a nice optic, I just don't like the lack of flexibility of a fixed magnification. That is why I think the VCOG is going to be such a hit.
The Eotech is a good optic, and with a magnifier you have flexibility to do short or longer range shooting. You could of course obtain the same results by adding an RMR to your ACOG setup. Just a thought.
