The ROMEOZero-ELITE shares the same ultra-compact size and mounting footprint* of Sig Sauer's popular ROMEOZero micro red dot, but is loaded with a host of premium upgrades. Starting with the scratch-resistant glass aspherical lens delivering unmatched clarity and a distortion-free sight picture when compared to competitors, the proprietary carbon-infused polymer housing with reinforced lens area also gives the ROMEOZero ELITE an even greater level of drop protection, making it incredibly rugged. The optic also comes with a hardened steel protective shroud for an even greater level of durability. The ROMOEZero ELITE features the brand new circle-dot reticle for even faster, more instinctive acquisition and our new T.A.P. (Touch-Activated Programming) technology gives the user the ability to change brightness and reticle options 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 SuperLuminovaA(R) pigment for visibility in dark environments. And just like our original ROMEOZero, the new ROMEOZero ELITE is fully assembled in the U.S.A. in Sig Sauer's state-of-art facility in Oregon.FEATURES:Carbon-Infused WeaponsGrade Ultralight Polymer Housing with the ROMEOZero/ Shield RMSc Footprint, Provides Increased Shock and Drop ProtectionCompatible with Springfield Hellcat OSP & GLOCK G43X MOS PistolsAspherical Glass Lens with Zero DistortionCircle-Dot or Single Dot Reticles For Fast Target AcquisitionT.A.P.
