Key Features
Reticle System
The ROMEO4XT-PRO features an advanced, user-selectable reticle system. Operators can choose between a highly efficient 65 MOA Circle with a 2 MOA Dot, a standalone 2 MOA Dot, or a 65 MOA Circle. This versatility allows for rapid target acquisition at close quarters and precise engagement at extended ranges, adapting to diverse operational requirements. The 10 daylight and 2 night vision compatible illumination settings ensure optimal visibility across all lighting conditions.
Construction and Durability
Constructed from robust 7075-T6 aircraft-grade aluminum, the ROMEO4XT-PRO is engineered to withstand extreme environmental and operational stresses. Its sealed design ensures IPX-8 waterproof performance, capable of submersion up to 20 meters for 30 minutes, and is fully fog-proof. This robust construction guarantees sustained reliability in austere environments, meeting the demands of duty applications.
Optical Performance
Equipped with a high-efficiency red LED illumination system and SIG SAUER’s proprietary SpectraCoat™ lens coatings, the ROMEO4XT-PRO delivers exceptional clarity and light transmission. The parallax-free optical design ensures the point of aim remains consistent with the point of impact, regardless of eye position.
Power Management
Utilizing a single CR123A battery, the ROMEO4XT-PRO boasts an impressive 50,000-hour battery life at a moderate setting. SIG SAUER’s MOTAC™ (Motion Activated Illumination) technology conserves battery power by shutting down illumination when idle and instantly powering up upon detecting motion, maximizing operational readiness.
Mounting and Integration
The optic integrates seamlessly onto MIL-STD-1913 Picatinny rails via an included quick-detach (QD) mount. This mount provides a lower 1/3 co-witness height, facilitating integration with standard iron sights while allowing for rapid deployment and removal without loss of zero.
