Product Info for SIG SAUER Romeo4B 1X20 Low/Co .5MOA

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. Romeo4 sights are parallax-free so point-of-aim is point-of-impact and the red dot remains parallel to the bore of your firearm, no matter what your viewing angle is relative to the optical axis of the sight. Unlimited eye-relief allows you to acquire the aiming point and the target regardless of the position of your eye behind the sight. 5000+ hour battery life and the readily available CR2032 battery is side-loading, allowing for quick battery replacement. Dependable waterproof (IPX-7 rated for complete water immersion up to 1 atmosphere) and fog-proof performance.image

Features of SIG SAUER Romeo4B 1x20mm Red Dot Sight Low/Co .5MOA SOR41101:

  • Stealth ID 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.
  • Highly efficient, ultra-wide broadband, anti-reflection Spectracoat lens coatings reduce surface reflections to extremely low levels across the entire visible spectrum providing superior light transmission.
  • Unlimited eye-relief allows you to acquire the aiming point and the target regardless of the position of your eye behind the sight
  • Dual reticle option, on select models, toggle between 2 MOA red dot or circle dot (2 MOA red dot with 65 MOA circle)
  • Utilizes an ultra-efficient red LED illumination system for daylight visibility with extended runtime and mil-spec objective coatings to limit downrange light leakage in tactical situations.
  • Features MOTAC (Motion Activated Illumination System) that powers up when it senses motion and powers down when it does not. Provides for optimum operational safety and enhanced battery life
