The GhostHunter Night Vision Adapter from Sightmark enables a GhostHunter monocular to be attached to the eyepiece bell of a riflescope. This adapter is compatible with the 1x24 and 2x24 models of the GhostHunter night vision device. Included with this night vision accessory is a coupler adapter for pairing the NVD and scope, as well as a set of five reduction rings that permit the shooter to connect the monocular to riflescopes of various sizes. An integrated Weaver rail atop the adapter will accommodate a compact shooting accessory like an infrared illuminator. The coupler clamps to the scope using a textured thumbscrew, and the GhostHunter monocular locks in place via a throw-lever.
