Calculated Kinetics Holosun K Optic Plate System with Iron Sight Features The Calculated Kinetics Optic Plate System with Iron Sight is machined to match the Holosun EPS footprint giving MAC DS1911 owners a secure purpose-built mounting solution rather than a generic adapter plate. Fitting an optic plate to the MAC 9 DS series has historically been straightforward but achieving a proper co-witness has been the harder part and this plate is designed to solve exactly that problem. When paired with a DOGTAG plate the system allows the slide-mounted iron sight to co-witness through the optic window giving the shooter a backup sighting reference if the red dot fails. The plate is finished in an anodized Black coating for durability against daily carry wear. Installation hardware ships with the plate including a Torx bit sized to the mounting screws and a small tube of Vibratite thread locker to keep the screws secure under recoil. This keeps the shooter from needing to source separate tools or thread locker to complete the job correctly. Built specifically for the MAC DS1911 platform the plate mounts with a precise repeatable fit that keeps the optic zeroed through hard use. The Calculated Kinetics Optic Plate System with Iron Sight gives MAC DS1911 owners a dependable co-witness capable optic mounting solution for sale at GrabAGun.
