The SIG Sauer ROMEO-X SIG-LOC PRO Reflex Sight, Green Circle Dot (SIG Sauer part no. SORX1570) is a fully enclosed 1x reflex sight that mounts on the SIG-LOC PRO footprint and shows a green circle-dot reticle. SIG developed SIG-LOC with the ROMEO-M17 and built it to give five points of contact between slide and optic, so recoil and impacts are less likely to shift your zero. The housing is 7075 aluminum around a sealed optical system with a distortion-free aspherical lens. It is a strong match for a duty, carry or range pistol that has a slide cut for the SIG-LOC PRO footprint.

Key Specifications

• The reticle is a green circle dot, a combination that is quick to find and easy to center on the target.
• The mounting footprint is SIG-LOC PRO, which has five points of contact between the slide and the optic to hold zero under recoil.
• Magnification is 1x, the unmagnified view a pistol optic needs for fast two-eyed shooting.
• The objective lens diameter is 24 mm, giving a usable window to pick up the dot.
• Overall length is 1.9 inches (48.26 mm), a compact size for a slide-mounted sight.
• Height is 0.96 inch (24.38 mm), and SIG calls it the industry’s lowest deck height for standard-height iron sight co-witness.
• The housing is 7075 aluminum with a fully enclosed and sealed optical system, which keeps the emitter and lens protected.
• The lens is a distortion-free aspherical glass lens, which keeps the reticle crisp across the window.
• Illumination offers 15 settings, including 3 dedicated night-vision settings, and MOTAC motion-activated illumination wakes the dot when the pistol moves.
• Battery life is rated at 20,000 hours with a side-load battery, so you can change it without removing the optic.
