Calculated Kinetics Hellcat Holosun K/RMSc Adapter Plate

Springfield Hellcat Optics Mounting Solution

The Calculated Kinetics adapter plate transforms your Springfield Hellcat OSP into a modern optics-ready platform. This precision-machined component bridges the gap between your pistol and contemporary red dot sights.

Key Features

• Holosun K and RMSc Footprint Compatible — Accepts a wide range of modern compact optics
• Full Recoil Lugs — Engineered for stable, repeatable mounting that handles recoil forces
• USA Manufacturing — Machined domestically to exacting standards
• Hard Anodized Finish — Black anodized coating resists corrosion and wear for decades of reliable service
• Precision Fit — Designed specifically for the Hellcat OSP platform

Practical Considerations

The factory iron sights on the Hellcat are minimal by design. Pairing this adapter with a quality optic—such as the Ameriglo SA 504 for proper co-witness capability—creates a genuinely usable sighting system. This combination gives you both speed and precision in a compact package.

Whether you're building a carry gun or a competition platform, this adapter plate provides the foundation for a modern, efficient Hellcat setup.
