The Vortex Viper 1x24 mm 6 MOA Red Dot Sight is not compatible with the Hellcat Pro OSP. The Hellcat Pro OSP fits optics with the micro RMSc footprint. Direct fit options include the Sig Romeo Zero, Vortex Defender, Shield RMSc, Viridian RFX-11 and more.

Unfortunately no. The Hellcat would work with the Defender-CCW, however, and it would be a direct-to-slide fit, otherwise!

The Vortex Viper uses the Docter/Noblex red dot sight footprint standard.

You may be able to get a mounting shim/plate for this optic, but that is a question for Springfield Armory.
