I recently purchased a TA33R-8 compact model ACOG. I've been wanting an ACOG for quite a while, and have been eying this model for quite some time. It fit all of my requirements, and then in a moment of "weakness" I grabbed one when it went on sale on Black Friday.
When I first looked through the reticule I thought that it might be slightly off, but figured that it was only because it wasn't mounted. I dropped it onto the only rifle I had in the shop (Delton upper) to see how it worked out. Unfortunately as soon as I got it on to the rifle I could tell that it really was canted - the reticule is rotated a few degrees counter-clockwise (far enough to mess with accurate shooting). Later when I got home I tried it out on several different uppers, of differing brands with no better luck, I am quite sure its the optic, not my rifles.
So, might there anything I can do about it? Might the problem be the mount? (its the standard flattop adapter that came with the scope). I'm really rather disappointed, as this is not something I expected with a scope this expensive. On the other hand, its crystal clear, I really like the reticule and BAC is awesome.... Ah well, just my luck....
