This is a lightweight housing for a night vision eyepiece diopter. It is sold as a single diopter and does not include the optic. It is only the housing.
It is meant to replace the mil-spec diopter. It cuts the weight of the diopter assembly by 55%, or the weight of the entire mil-spec eyepiece assembly by 15%. It can be used with an eyepiece locking ring or with the set screw located on the diopter.
