When the action is fast, target acquisition and accuracy are paramount and the Sig Sauer Romeo1 is the answer. This red dot sight isn’t ideal for mounting to a handgun, AR-15, pistol caliber carbine, or any other rifle when speed and accuracy at close distance is the goal.

The miniature, open reflex Sig Sauer Romeo1 red dot sight withstands the punishment of deployment while maintaining a confident zero. TruHold twin adjustment springs provide a lock-less zeroing system that keeps the Romeo1 red dot on-target shot after shot. The adjustable brightness 3 MOA red dot is an excellent size for balancing speed and accuracy.

The ROMEO1 red dot is designed to fit the most popular pistols, or you can mount this red dot low and co-witness your iron sights on a SIG SAUER pistol with a custom-machined slide. The Romeo1 is CNC-machined from a solid billet of Magnesium for a lightweight design without sacrificing any strength. The molded aspherical lens is bright and distortion free, and the red-notch coating ensures a brilliant red dot for fast target acquisition.

The Sig Sauer ROMEO1 red dot features manual brightness controls and auto power on and off through Sig Sauer’s MOTAC (Motion Activated Illumination). The MOTAC technology automatically powers off the reflex sight’s red dot when no motion is sensed and turns it back on when movement is sensed. This preserves the red dot’s battery life while ensuring this red dot is always ready for action. The ROMEO1’s red dot is powered by a top-loading CR1632 battery so you never have to lose your red dot’s zero to change a battery.

The SIG SAUER ROMEO1 Miniature Reflex Sight is the ideal red dot sighting solution for the modern semi-automatic pistol.
