This steel optic mount adapts the Holosun 509T (and 509T X2) to CZ P-10 series optics-ready slides. The factory P-10 footprint uses a RMR-style pattern; the 509T uses a proprietary lug system. This mount bridges that interface directly, eliminating the need for aftermarket slide milling or adapter plates that add height. Machined from billet steel with a black oxide finish, it maintains zero retention under recoil and resists corrosion in duty or competition use. The mount replaces the factory cover plate and uses the existing screw holes — no slide modification required.

FAQ
Does this mount work with the Holosun 507C or 508T?
No. This mount is specific to the Holosun 509T footprint. The 507C and 508T use a standard RMR pattern and mount directly to the P-10 optics cut without an adapter.
Will this mount co-witness with factory CZ P-10 iron sights?
Yes. The mount is designed to keep the optic deck low enough to co-witness with standard-height P-10 suppressor sights. Factory P-10 irons will appear at the very bottom of the window on most 509T models.
Can I use this mount on a P-10 that was not factory optics-ready?
No. This mount is designed exclusively for slides with the factory CZ P-10 optics cut. Non-optics slides require slide milling to accept a red dot.
