When purchasing Spuhr or any other brand from eGoods365.com store, you can be sure that (a) you are purchasing from US based company with the most responsive and friendly customer service; (b) an authentic, not a counterfeit and not a refurbished product.

The Spuhr ISMS Rangefinder Adapter lets you put a Wilcox RAPTAR, SilencerCo Radius, or other similar rail-mounted rangefinder over your scope. Machined from strong, yet lightweight aluminum, the ISMS Rangefinder Adapter is a solid platform that bolts to the forward ring cap of a Spuhr ISMS scope base. The bottom is angled to clear the objective lenses of most scopes, preventing any interference with the optic.


3.35" Picatinny rail with 8 mounting slots give you versatility in positioning the rangefinder

Hardcoat anodized finish, matte black, blends with most scopes and rifle receivers

Puts the rail slots slightly less than 1" above the scope, requiring minimal-to-no movement of your head to read the rangefinder

Only 1.5 oz. so it won’t weigh down your rifle


With the Spuhr ISMS Rangefinder Adapter holding a rangefinder directly over your scope, you can get instant target measurements for pinpoint, long-range accuracy.
