Protect the eyepiece lens on your Trijicon 4x32 ACOG riflescope, with or without integrated bosses mounting a red dot sight, with the Eyepiece Flip Cap from the same manufacturer. This matte black, non-see through cover provides a snap-lock lid that prevents dust build up and blocks rain and snow accumulation when closed. The lid pivots a full 270 degrees to lay parallel to the scope so it doesn't block the shooters view.
