Ahhh. I have the [Romeo5X](https://op1.0ps.us/365-365-ffffff/opplanet-sig-sauer-opmod-romeo5-x-1x20mm-compact-red-dot-sight-2-moa-dot-reticle-flat-dark-eart-main.jpg), which looks just like that except black. And I'll be honest I didn't know there were different versions of the 5. I'm sorry brother but I can't speak on that mount other than to say get something more solid.
