Romeo4

ROMEO4 is the ultimate red-dot sight when fast, accurate target acquisition is a must. Whether it’s a moving target, dangerous game at full charge, or a fast breaking tactical 
situation at close quarters. When things are moving fast and you need to get on target in 
a hurry, your sight has to work faster. No matter the lighting conditions, weather 
conditions, or terrain, the ROMEO4 red-dot sight has you covered-—when it counts. 
You can shoot with confidence with both eyes open, on target yet aware of the situation 
at all times as it unfolds. And because it is a SIG SAUER®, you know the ROMEO4 
is as tough and dependable as our firearms.

Electro-Optics Technology

We have developed truly game changing optics for all types of shooters: military, law enforcement, hunters, and competitive shooters.

  • Infinite Guarantee™ Icon

    Infinite Guarantee

    SIG SAUER Electro-Optics are guaranteed forever. It's an unlimited lifetime guarantee.

  • Motac™ Icon

    Motac™

    Activated through motion sensing technology, MOTAC immediately powers up illumination when it senses motion and powers down when it does not in order to extend battery life.

  • SpectraCoat™ Icon

    SpectraCoat™

    Highly efficient, ultra-wide broadband, anti-reflection lens coatings reduce surface reflections to extremely low levels across the entire visible spectrum providing superior light transmission.

  • Stealth ID™ Icon

    Stealth ID™

    Electro-Optics industrial design inspired by our legendary firearms; deflection armor trapezoidal surfacing breaks up the shape and visibility of the optic along with pistol slide serrations and grip checkering to add function to the form of all SIG SAUER electro-optics.

  • 5 Year Warranty Icon

    5 Year Warranty

    (Electronic Component Limited 5 Year Warranty) Covers any defects in materials and workmanship in the electronic and Tritium components of illuminated riflescopes/sights, pistol sights, electronic sights, flashlights, lasers, binoculars, spotting scopes and rangefinders for five years from date of manufacture.

  • Quad Reticle

    Quad Reticle technology allows the user to toggle between four different selectable reticle options. With the Ballistic Circle Dot reticle, users can pick between a 2 MOA dot, a 2 MOA dot with ballistic holds, a 2 MOA/65 MOA Circle Dot or a 2 MOA/65 MOA Circle Dot with ballistic holds. These ballistic holdover points subtend for the 5.56 NATO and 7.62x51mm NATO cartridges. Meanwhile, the Circle Plex quad reticle offers similar aiming options, but the 2 MOA dot is swapped for a 1 MOA central aiming feature in a plex-type reticle for more precise mid- to long-range shooting.

  • Solar Powered Illumination System

    Highly efficient solar panel combined with advanced micro-electronic power management system augment the on-board battery to power-up illuminated reticles with ambient light load. Ruggedized with impact and scratch resistant glass.
