That scope has been on the Andrews for quite some time (years) so it's not new. I seem to remember reading some negative comment somewhere, but it may simply have been questioning the 'risk' of keeping four elements aligned properly.
Of course, now we have six-element scopes but their robustness in maintaining alignment over time remains to be seen.
