The ROMEOZero-PRO features a proprietary carbon-infused polymer housing with a reinforced lens protection area making it incredibly durable while delivering significant drop and impact protection. It also comes with a hardened steel protective shroud for even greater protection and durability. The ROMEOZero-PRO is 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.
