The Sig Sauer Romeo 4T-Pro is a compact, high-performance red dot sight designed for rapid target acquisition in a variety of lighting conditions. Built with a 20mm objective lens and featuring a Ballistic Circle Dot reticle, this optic combines a 2 MOA red dot with a 65 MOA outer circle for versatile aiming options.

Equipped with MOTAC (Motion Activated Illumination), the Romeo 4T-Pro automatically activates when motion is detected and powers down during periods of inactivity to preserve battery life. The sight offers 9 daytime and 3 night vision brightness settings to adapt to any environment.

Constructed with a mil-spec standard and protected by Sig Sauer's SpectraCoat, LensArmor, and D.A.R.C. optical coatings, this optic delivers exceptional clarity and durability. The IPX-8 waterproof rating ensures reliable performance in wet conditions.

Mounting is simple with the included hex bolt mount and spacer, compatible with standard M1913 Picatinny rails. The Romeo 4T-Pro operates on a single CR2032 battery with an impressive up to 50,000 hour runtime.
