I've got the TA01NSN model. It doesn't have that BAC reticle - it has the crosshairs with the BDC calibrated for an M-4 w/ 62gr rounds. I love my ACOG and have nothing negative to say about it. But I do wonder sometimes how I convinced myself to spend $800 for such an optic. But damn is it cool.
The TA31s have the BAC reticle with a built in BDC and they are very popular scopes. Trijicon is top notch for the type of optics they make. You also might want to look into the new variable power Elcan that's supposed to be pretty nice.
