I recently purchased the Nikon M223, which is very similar to the African. Mine does not have the 223 BDC, it has the one large dot in the middle. I actually like this because at 1x magnification, not only is it a true 1x, but the reticle actually acts kinda like a red dot sight.
The glass is clear and the knobs work nicely. My only complaint is the magnification adjustment is really stiff, but I assume that will break in.
If you do get the 223 I would recommend the Nikon mount for it. It's $75, but worth it to have the scope with the correct angle when mounted.
