Sig Sauer Electro-Optics Romeo4T Pro 1x20mm 2 MOA/65 MOA Quad Ballistic Red Dot - Flat Dark Earth

The Sig Sauer Electro-Optics Romeo4T Pro is a battle-proven 1x20mm red dot sight finished in Flat Dark Earth and engineered for hard, professional use on modern semi-auto pistols, MSR platforms, and shotguns. Designed, built, and tested to mil-grade standards, it pairs a compact 20mm objective with an unlimited field of view and unlimited eye relief for fast, both-eyes-open target acquisition.

At the heart of the optic is the 2 MOA Red Quad Ballistic Dot / 65 MOA Circle reticle, which gives the shooter a precise 2 MOA center dot for accuracy, a surrounding 65 MOA circle for rapid close-quarters work, and dedicated ballistic holdovers for compensation out to distance. The reticle is powered by a CR2032 battery with motion-activated illumination delivering up to approximately 50,000 hours of runtime, and top-mounted buttons for quick brightness adjustment.

Optics are protected by Sig Sauer's proprietary D.A.R.C. (Dark Adaptive Reticles and Coatings), LensArmor, LensShield, and SpectraCoat lens treatments, providing elite performance in bright light and under night vision. Windage and elevation adjustments click in clean .50 MOA increments, and the sight is fully waterproof for reliable field use. The Romeo4T Pro measures just 2.66" long and weighs 6.30 oz, keeping it compact and lightweight atop any host platform.
