Optic Compatibility — RMSc Footprint

Optic Mounting Hardware

• Optic mount screws: 6-32 × 7/16"

For optic installation: use the mounting kit included with your optic (Holosun, Trijicon, Sig, Vortex, etc.) — manufacturer kits have the correct torque spec, head shape, and threadlocker matched to that optic.
