Feeling like a dummy here.
My Sig Sauer Romeo5XDR just showed up, and I’m trying to mount it to the rail on my M*CARBO optic mount. I removed the little screw and plate thingy on the optic’s base. But the optic just…won’t go onto the rail.
If I try mounting the optic on the rail on the rifle itself, it goes on fine – drops right on, no need to force it at all.
Below is a photo of as close as I can get it with the MCARBO mount. I can’t get it to sit flush at all. (Photo isn’t great, but I had a hard time getting a good angle.)
Any suggestions? Am I overlooking something super obvious?
