SIG SAUER Romeo-X 1x24mm Reflex Red Dot Sight 32 MOA Circle with 2 MOA Green Dot Black For SIG-LOC Footprint. Designed for precision and strength SIG-LOC ushers in a new era of expectation and performance for civilians and professionals with the ROMEO-X SIG-LOC pistol-mounted red dot. SIG-LOC is an innovative mounting footprint that establishes five points of contact between the slide and optic to eliminate shift in zero created by extensive shock from recoil and harsh impacts. The unique bottom-mounted design allows for a longer focal length that dramatically reduces parallax and reticle distortion to provide an incredibly forgiving shooting experience. With SIG-LOC you re investing in technology that has been vetted and trusted by the most demanding users in the world ensuring superior accuracy and reliability in every situation. Pistol slides that are configured with SIG-LOC mounting footprints are still fully compatible with traditional top-mount reflex sights.
