Calculated Kinetics Adapter Plate Features The Calculated Kinetics Adapter Plate is machined specifically for the Springfield Armory Hellcat Pro OSP and RDP slides giving the pistol a secure mounting surface for Holosun K and RMSc footprint optics. Full recoil lugs on the plate provide a stable mount that keeps the optic locked in zero through repeated firing. It is compatible with widely used micro red dots including the Holosun 407K 507K EPS Carry and SCS Carry giving Hellcat owners real choice in optic selection. Because it is purpose built for the Hellcat footprint installation is a straightforward bolt on upgrade rather than a custom machining job. Machined in the USA and hard anodized in black the plate is built to survive the wear of daily carry and the recoil impulse of a compact 9mm pistol. The package includes mounting hardware torx bits vibratite thread locker and instructions giving the installer everything needed to complete the job at home. Calculated Kinetics notes the factory iron sights on the Hellcat are difficult to use once an optic is mounted and recommends a taller sight set for proper co witness. This adapter plate is a practical affordable way to add red dot capability to the Hellcat platform.
