Calculated Kinetics - Hellcat OSP to Holosun 407K/507K/EPS Carry Adapter Plate

Hellcat Adapter Plate for your Springfield Armory OSP from Calculated Kinetics is the Adapter you want! Our 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 we recommend using the Ameriglo SA 504 for a proper co witness.

ALL adapters, optic plates, and DOGTAGs come with all hardware, Torx bits, Vibratite, and instructions to properly install your optic. 

Screws for the EPS Carry are now included! No need to purchase extra screws.
