I never did update the thread with my mount and lens cover findings.
I used the MI TA33/TA44 ACOG mount I linked above, it works well. I also found two Butler Creek flip-up covers that work so long as you use PA’s ARD, both are eye objective style (without the little thumb lever) - 02A front, 05 rear.
I like this little 3X optic enough that I am very seriously thinking of putting them on two more uppers replacing 1x red dots and magnifiers, my 9” .300 and 11.5” 5.56.
