FN 42mm Cover Ring Adapter - Metallo

Cover Ring Adapters N are special mounting units, which allow the installation of Forward F accessories in front of the lens for day optical devices (spotting scopes, telescopes and binoculars). The adapters are supplied with a set of insertion rings (the choice of insertion rings is defined by the outer diameter of the lens housing of the optical device). After installation, the adapter remains permanently on the lens of the optical device, which allows the thermal part of the digital accessory to be easily installed in front of the lens. During the day, when the accessory is not in use, the adapter serves as an insert for the protective cover (included in the package), which protects the eyepiece of the day scope.
