NcStar 4-Reticle Reflex Black Sight w/ QR Mount Red-Colored Reticle Set 194621. While most Red Dot Sights have just a dot in the middle this one lets you switch between a dot starburst cross and bullseye reticle letting you customize the sight to match your preferences and environment. It attaches to Picatinny/Weaver mounts and uses a CR2032 battery so it's standard issue when it comes to most red dot sights. The lightweight durable aluminum minimizes the amount of weight you add to your weapon so you don't have to worry about losing any handling or maneuverability.
