Questions & Answers
Will a Holosum 507c work to mount on Ruger Mark IV

Absolutely! Mine dropped right on my Mark 4 Target.

by Wild Wally, Verified Owner, March 30, 2026
Will a Holosun SCS MOS fit on this mount?

No. The Glock MOS footprint is very different from the 4 footprints that this mount does work with.

GREAT PLATE FOR MY RUGER MARK IV TARGET by DrRandy, Verified Owner, October 5, 2024
Solid aluminum construction. Holds tight with the enclosed screws. Mounting my SwampFox green dot was a snap. The side benefit point of aim was right on. No adjustment was needed.

Helpful Negative Review
This mount does not fit a Ruger Mark IV 22/45 Tactical as advertised. Purchased to mount a Holosun HS507K X2 to my Ruger pistol.

Must have for optics by Tip, Verified Owner, April 4, 2026
This product is great because of the multiple footprints for reflex red dots. I really wish all the manufacturers could just compromise on one footprint it would make it easier and they could if they wanted to.
