Calculated Kinetics RMR Optic Plate System with Iron Sight Features The Calculated Kinetics RMR Optic Plate System is machined to accept the widely used Trijicon RMR footprint letting MAC DS1911 owners mount a compatible red dot directly to the slide. Co-witnessing with the factory iron sight is a common point of frustration on MAC 9 platforms and this plate is designed specifically to make that alignment achievable. The black anodized finish resists corrosion and wear keeping the plate looking clean through regular carry and range use. Because the plate is purpose built for the MAC DS1911 it mounts with the precision and fitment that a universal adapter cannot match. Every plate ships complete with the mounting hardware needed for installation a Torx bit sized to the screws and a small tube of Vibra-Tite thread locker to keep everything secure under recoil. That means an owner has everything required to complete the installation without sourcing additional parts or tools separately. The inclusion of the iron sight component keeps a usable backup sighting system in place even with an optic mounted. The Calculated Kinetics RMR Optic Plate System is for sale at GrabAGun for MAC DS1911 shooters ready to add red dot capability to their pistol.
