Frequently Asked Questions

What is required to mount the Cyelee Ghost HDG on a Sig Sauer M17?

Mounting the Cyelee Ghost HDG on a Sig Sauer M17 requires an EGW RMR adapter plate (Part #49500) because the M17 has a proprietary optic footprint that is not directly compatible with the RMR standard.

What are the key features of the Cyelee Ghost HDG red dot sight?

The Cyelee Ghost HDG features a 7075-T6 aluminum body, IPX7 waterproof rating, a side-loading battery tray for a CR1632 battery, shake-awake functionality, and a multi-reticle system offering a 2 MOA dot, 26 MOA circle, or both.

Why is the Ruger Max 9 incompatible with the Cyelee Ghost HDG?

The Ruger Max 9 uses the RMS-C footprint for its optic mounting, while the Cyelee Ghost HDG requires an RMR footprint. These footprints are not interchangeable without specific adapters, making the Max 9 incompatible out-of-the-box.

What safety precautions should be taken during optic installation?

Always ensure the firearm is unloaded and safe to handle before starting installation. Use blue Loctite on mounting screws to prevent loosening, and tighten screws to the manufacturer's recommended torque specifications to avoid damage.
