This Calculated Kinetics adapter plate converts a SIG P211 GTO or P320 slide cut for the Romeo 1 Pro footprint to accept RMR-footprint optics, so shooters can mount a Trijicon RMR or another RMR-pattern red dot on their pistol. The front dovetail hooks securely under the slide and integrated recoil lugs keep the optic from twisting under recoil.
Machined for a precise fit and finished in hard anodized black for corrosion resistance, the plate comes as a complete kit with 6-40 screws, a Torx bit, Vibratite threadlocker, and an installation card.
