C&H Precision P320 X-FIVE RMR 10-8 Rear-Sight Mount

A Sig P320 X-FIVE/M17/M18 and RMR/Holosun C setup calls for a plate cut for both sides of that interface, and the C&H Precision P320 X-FIVE RMR 10-8 Rear-Sight Mount fills that role. This version is finished in anodized black and is intended for the exact compatibility shown here. The package includes mounting hardware and a 10-8 rear sight.

With Sig P320 X-FIVE/M17/M18 adapter plates, small changes in the slide cut can change the required part. The same is true on the optic side, where RMR/Holosun C has its own mounting geometry. Checking both standards together helps avoid a near-match that does not belong on the setup.

Use this plate only when the host is the listed Sig P320 X-FIVE/M17/M18 and the optic uses RMR/Holosun C. That keeps the installation tied to the intended interface instead of relying on a plate that is merely close in shape. More optics and rangefinders are available for other handgun and optic pairings.
