Abstract: A device attached to the sighting end of a telescopic sight prevents light from entering into the space between the sighting end and the eye of the user. The device includes an attachment member that slidingly and adjustably receives the sighting end, an eyepiece that is angled forwardly toward the user by about eight degrees when in repose so that when an eye socket of the user is placed against the eyepiece, the eyepiece flexes rearwardly by about the same angle so that the view through the device is perfectly aligned with the telescopic sight, and a recoil-absorbing means disposed between the trailing end of the attachment member and the leading end of the eyepiece. The eyepiece has a greater breadth than the attachment member, so the recoil member is stepped upwardly in diameter from the attachment member to the eyepiece.
