DN Cover Ring Adapters are special mounting units, that enable installation of Core FXQ attachments in front of the objectives of day optic devices (riflescopes, spotting scopes and binoculars).
Adapters are supplied with a set of insert rings (the choice of the insert ring is defined by the outer diameter of the objectives housing of optic device). After installation the adapter stays constantly on the objective of optic device which allows installing the thermal or digital attachment in front of the objective swiftly. During the day when the attachment is not used, adapter serves as the mount for the protective cover (included in the package), which protects the optics of day riflescope.
