The ROMEOZero Update is based on direct user feedback, the ROMEOZero Auto-Off has been reengineered for everyday concealed carry and pistols with slim slide profiles.The sight features a ruggedized, WeaponsGrade textured polymer body with a new aspherical glass lens that drastically increases scratch resistance while eliminating optical distortion. In addition to the upgraded lens, this optic can be configured by the user to run a 16-hour Auto-Off or a Constant-On setting. Auto-Off requires the user to manually turn the optic on after timing out at the 16 hour limit, while Constant-On requires the user to manually turn the sight on and off at their discretion.
