Calculated Kinetics CK P211 GTO/P320 R1 PRO to RMR Plate – Direct Mount Adapter

The Calculated Kinetics CK P211 adapter plate allows shooters to mount RMR-pattern optics directly to SIG Sauer P320 R1 PRO pistols equipped with the R1 PRO optics cut. This precision-machined plate eliminates the need for the factory adapter, providing a lower mounting height and more secure optic attachment for competitive shooting, duty use, or personal defense.

Machined from steel and designed specifically for the P320 R1 PRO optics footprint, the CK P211 accepts Trijicon RMR and RMR-compatible red dot sights. The plate includes all necessary mounting hardware for both the plate-to-slide and optic-to-plate attachment. Installation requires basic hand tools and following torque specifications outlined in the included instructions.
