Product Description Built for speed, these High Performance red dot sights will take your shooting ability to the next level. By using a single red dot as an aiming point, target acquisition is as simple as point and shoot. The unique Heads-Up-Display (HUD) design provides an unlimited field of view, while eliminating obstruction and tunnel vision common to tube style scopes. Designed around the 1911 frame and competition race guns, the Serendipity started the heads-up revolution in shooting sports. In 1993 it was the first sight ever used in competition to incorporate a heads-up display or "tubeless" design. Since then C-MORE Systems sights have proven their performance and reliability with multiple National and World Championships and continue to be the DOMINATE sight in competition today. The Serendipity is available in ten different models. The difference in each model is the intensity switch and the width of the mounting pads, which are machined to fit the width of the selected frame.
