Sig Sauer’s RomeoZero-Elite shares the same compact size and mounting footprint of the RomeoZero, but comes packed with a wide array of next level upgrades. It comes equipped with glass aspherical lenses for superior clarity and a distortion-free sight picture, with a carbon infused polymer housing for excellent drop and impact protection. One of the RomeoZero-Elite’s more notable improvements is Sig’s exclusive T.A.P. (Touch-Activated Programming). Holding the activation button down for 5 seconds will cause the reticle to start blinking, this allows the user to switch between the brightness settings by simply tapping the optic. Other features of the RomeoZero-Elite include anti-reflective grooves molded into the rear of the optic, as well as Grade A Swiss SuperLuminova pigment to serve as a reference point for use in dark environments.
