CK HELLCAT TO K/RMSC DT PLATE

Hellcat Adapter Plate for your Springfield Armory OSP from Calculated Kinetics is the Adapter you want! Their Adapter plate comes with Full recoil lugs to provide a stable mount. Machined right here in the USA and hard anodized give you a lifetime of use. The OEM iron sights are barely useable, and Calculated Kinetics recommends using the Ameriglo SA 504 for a proper co witness.
