Same lightweight polymer design of our ROMEOZero optics now for a full-size pistol. The R model fits RMR footprints. The ROMEOZero-PRO and ROMEOZero-R bring the lightweight polymer design of our ROMEOZero line of micro reflex optics to a full-size pistol optic all built with a host of premium features. The ROMOEZero-R model is compatible with all Trijicon RMR footprints. These new full size reflex optics feature a large 30mm aspherical lens made of scratch-resistant glass, offering unmatched clarity and a distortion-free sight picture when compared to competitors. Both feature a proprietary carbon-infused polymer housing with a reinforced lens protection area making them incredibly durable and deliver significant drop and impact protection. Both also come with a hardened steel protective shroud for even greater protection and durability. Both models are available with either a 10 MOA red dot or the versatile new circle/dot reticle. The new T.A.P. (Touch-Activated Programming) technology gives the user the ability to change brightness with just a tap on the optic. All rear surfaces of the housing have anti-reflection grooves molded in, including the backup rear sight notch which is marked with Grade A Swiss SuperLuminova pigment for visibility in dark environments. And just like our smaller ROMEOZero and ROMEOZero-ELITE models, the new ROMEOZero-PRO and ROMEOZero-R are fully assembled in the U.S.A. in our state-of-art facility in Oregon.
