This anti-reflective device is made of aluminum and threads directly in the objective end of the SRS sight for a secure fit. It weighs a light .63 ounces and adds a slim .27" to the length of the SRS. It does not make any changes to the height or the width. The KillFlash device should be used in any situation where light reflections from your objective lens could reveal your position. The visual of the optic from your eyes perspective should remain unchanged.
