The Sig Sauer Romeo4T Solar 1×20 Circle-Dot Red Dot, FDE (brand part no. SOR43131) is a rifle-mounted reflex sight with a solar-assisted power system that extends battery life under normal daylight use, from Sig Sauer. Its multi-reticle ballistic circle-dot pattern combines a 2 MOA center dot with a 65 MOA circle, giving a shooter both a precise aiming point and a fast-acquisition reference for close-range work. A half-inch hex-bolt mount keeps the optic secure on a rifle’s top rail, and SpectraCoat lens treatment keeps the glass clear across lighting conditions. This listing is filed under our Lights & Lasers class in our catalog, but it’s a genuine rifle red dot optic, not a light or laser — written up accordingly.
