I've seen conflicting reports on what the reticle actually looks like for the Z-plus RD. Meopta website shows an open square box whereas people have posted PDFs that show a solid circle for the center. I emailed them yesterday about what it actually looks like and they sent me this PDF. This shows an open circle and they state in the description it is 1 MOA, but over on the dimensions they declare it to be 1.5 MOA. No idea which one is correct, but relieved to know it is open and not solid at least.
