Frequently Asked Questions

How do I properly install an optic on a CZ Shadow 2 Orange?

Begin by ensuring the firearm is unloaded. Remove the factory optic cover, install the RMR plate, apply Loctite to the Holosun 507C screws, mount the optic, and use a Wheeler FAT Wrench to torque the screws precisely. Apply witness marks to monitor tightness.

What tools are needed to mount a red dot sight on a CZ Shadow 2 Orange?

For mounting a red dot like the Holosun 507C on a CZ Shadow 2 Orange, you'll need a Wheeler FAT Wrench for accurate torque application, Loctite thread locker, and a permanent marker for witness marks. Ensure you have the correct RMR footprint mounting plate.

Why are witness marks important when mounting a firearm optic?

Witness marks are crucial because they provide a visual indicator to quickly check if optic mounting screws have loosened due to recoil. Drawing a line across the screw head and the mounting surface allows for immediate detection of any shift, ensuring optic stability.

What is the correct torque specification for mounting a Holosun 507C?

While specific torque values can vary by mounting plate manufacturer, a common range for RMR-footprint optics like the Holosun 507C is 15-20 inch-pounds. Always consult the documentation for your specific mounting plate and optic for precise recommendations.
