Vortex Red Dot Sights are all about value. Vortex optics has made the needs of their customers their primary focus. They feel the best way to fulfill these needs is to provide the highest performance and fullest set of features in a reflex sight at a reasonable price. No other gun sight will get you on target faster than a red dot by Vortex. These parallax-free sights enable you to keep your eye on your target, rather than adjusting to the sights on your gun. Vortex Sights are waterproof, fogproof, and shock proof, so you can rely on them to perform regardless of the conditions. Additionally, the low power nature of red dot sights means you don't have to worry about power failure at an inopportune moment. If you want to learn more about red dot sights, feel free to contact us with any questions and one of our OpticsPlanet product specialists will lend you their expertise. And remember that all Vortex Reflex Sights receive free shipping!
