This sight looks exactly like the Sword Sight. Go for the Sword Sight. It''s the same price as the RT900 and it comes with a light. They have great service. The light that came withmy sight finally went out (the bulb, not the batteries) and they sent me a whole new light instead of just a bulb! I shoot the Hunter version, the one that's like the RT900. They also have sights with a third axis, if you're into 3D shooting. AND, you can get pins that are .029, .019 or .010!
