ROMEO4T-PRO Mil-Spec Red Dot Sight
The ROMEO4T-PRO offers the same high-end optical performance, quad-reticle, and legendary durability as the original ROMEO4T while adding key features requested by professionals. Illumination control moves to the top, providing easy access with either hand while staying clear of chest rigs and plate carriers when slung. A dedicated night vision override switch makes short work of drastic changes in lighting conditions and by combining MOTAC with a common CR2032 battery, the ROMEO4T-PRO is rated for 50,000 hours of runtime.
Available in Black and FDE.
