The Sig Sauer Romeo5 Gen II elevates red dot performance with advanced green dot technology that provides superior visibility across diverse lighting conditions. This 1x20mm optic delivers the proven reliability shooters demand with enhanced features that address real-world tactical and sporting applications.

What Makes This Different

The Romeo5 Gen II incorporates Sig's MOTAC (Motion Activated Illumination) system that automatically activates when motion is detected and powers down during periods of inactivity. The green dot reticle offers improved contrast against natural backgrounds compared to traditional red dots, particularly beneficial for users with red-green color vision deficiencies. Battery life extends to 40,000+ hours on medium settings, significantly outlasting competing optics in its class.

Key Features

  • 2 MOA green dot reticle for precise target acquisition and improved visibility
  • MOTAC motion-activated illumination with 40,000+ hour battery life
  • IPX-7 waterproof rating withstands complete submersion to 1 meter
  • Low-profile design with integrated lens caps and protective covers
  • 10 brightness settings including 2 night vision compatible modes
  • Standard Picatinny rail mount fits AR-15, AK, and shotgun platforms
  • Aircraft-grade aluminum construction with scratch-resistant lens coatings
Field performance demonstrates consistent zero retention through temperature extremes and recoil stress testing. The optic maintains accuracy across hunting applications, competitive shooting, and duty use scenarios. Fog-resistant lens coatings prevent internal condensation during rapid temperature changes, while the compact footprint preserves iron sight co-witness capabilities on most rifle configurations.
