No frills quality optic - Aimpoint ACO 2 MOA Red Dot Sight

This is a quality RDS without the little things that run the price up. It is the Aimpoint quality that everyone expects. This is a simple quality RDS that just works. There are better RDSs out there, but not for the price. My only complaint after zeroing and getting a little trigger time with it is that it is absolute co-witness. I prefer the lower 1/3 co-witness, but that is more about personal preference than the quality of the optic.
