A rare item. New in package FS2000 / F2000 integrated optics set. The infantryman outfitted with this will have reduced radar and thermal detection over a conventionally outfitted soldier. Includes scope and scope cover. This set will not fit a normal FS2000 without extensive gunsmithing. This will only fit rifles originally equipped with the integrated optic. The optic rail on the integrated optic rifles is entirely different from anything else.
