These Butler Creek 04 Objective Flip-ups worked on a Holosun HS503GU that I'm running on my Ruger PCC. I had to trim the rear/eye cover a bit but not the front and secured both with a few small dabs of Gorilla Gel Super Glue. Rear cover was tight going on but just fit. Used this procedure to trim the one cover down - https://imgur.com/a/ReTdB#Is1ZJwk. Going to buy a low 1/2" UTG Riser so that I can rotate the covers so they fold down instead of up to help prevent damaging them.
