Holosun 507C Picatinny Rail Mount for 407C/507C/508T

Holosun 507C Picatinny Mount is an optic mounting adapter designed to secure compatible Holosun reflex sights to a standard Picatinny rail. This mount converts an RMR-pattern optic footprint into a rail-mounted interface, allowing Holosun pistol-style red dots to be used on platforms that accept Picatinny-mounted optics.

Manufactured by Holosun, this mount is intended for users who want a stable, repeatable way to install Holosun 407C, 507C, and 508T optics on rifles, carbines, shotguns, or other Picatinny-equipped platforms. The mount provides a straightforward mechanical interface without altering the optic itself, making it suitable for range use, training setups, or non-slide-mounted applications.
