After it was all said and done, Optics Planet did have the GHW adapter in stock and got it to me today.
Up next is a Comp M5b, the PA/Holofun works fine, holds zero, and I just change the battery once a month. But I want something more robust and the quick change turrets for going super to subs and back will be cool...because in T-Minus 90 days I'll be putting a silencer in jail.
