Troy Industries Di-Optic Aperture sight

    Troy Industries have developed a nifty new diamond aperture rear sight for the AR-15.

    Troy claim the diamond shaped aperture helps the shooter acquire a sight picture faster than a round aperture.

    The DIO has two aperture settings, one for 300 meters and another calibrated for 550 meters. The price starts is $140 and it comes in a variety of colors.

    Thanks to Konrad for the info.
