The Spuhr Raptar/Radius Rangefinder ISMS Mount is a purpose-built adapter that lets you position a Wilcox RAPTAR, SilencerCo Radius, or similar rail-mounted rangefinder directly above your optic. Machined from lightweight aluminum with a matte black hardcoat anodized finish, it bolts to the forward ring cap of a Spuhr ISMS scope base and provides a rigid, low-profile Picatinny platform without disturbing your existing zero.

This adapter is optimized for 1 inch scope tubes and features a 0.25 inch ring height that keeps the rangefinder slightly less than 1 inch above the scope for easy reading with minimal head movement. The angled underside is designed to clear most objective lenses, while the 3.35 inch rail with eight slots offers flexible positioning for different rangefinder footprints. Ideal for precision rifle shooters and hunters who rely on accurate distance measurement, it reflects Spuhr’s reputation for thoughtful engineering and clean, functional design.
