The Romeo1 Reflex Sight is the solution for the modern semi-automatic pistol. The Romeo1 features a molded-glass aspheric lens with high performance coatings for superior light transmittance and zero distortion, as well as TruHold, a lockless zeroing system utilizing twin adjustment springs designed to endure handgun recoil and return to zero shot after shot. The MOTAC (Motion Activated Illumination System) utilizes manual controls that remember your last-used settings, powers up when it senses motion, and powers down when it does not, providing for optimum operational safety and enhanced battery life. The 3 MOA Red Dot with multiple intensity settings ensures rapid target engagement under a full range of lighting conditions. This sight is offered with an M1913 Rail Interface for use with today's MSR/AR platforms. Includes Keymod and M1913 Picatinny mount.
