The D3RS135, by Nc Star, is a 3-Rail Reflex Dot Sight. This is a unique sighting system has not only the Dot Sight, but also has 3 Tactical Rails mounted on the sight so that a shooter can mount other devices (such as lights or lasers) giving quick and easy access to a variety of devices as well as keeping the weight of the accessories closer to the center balance of the firearm avoiding the front heavy barrel feel of all the accessories mounted at the front end of the barrel on a Quad Rail.
Dot Reticle has three different Colors to choose from: Red, Green, and Blue, and is set at the proper AR-15 height to co-witness the Dot Optic with your Iron Sights. The Optic height will allow a more comfortable and natural cheek rest on your AR-15 stock.
This is the ideal solution for a shooter that wants a modular sighting system that allows the easy attachment of accessories to their Dot Sight.
Unlimited Eye Relief.
LED (Light Emitting diode) 100% safe for the eyes.
Fits virtually any Weaver/Picatinny rail, making it possible to fit onto a wide variety of firearms.
