The Bravo Combat Dot 3 MOA Red Dot Sight is available to order at the Echo1 USA Airsoft online store according to Jag Precision... "The Bravo 3 MOA Combat Dot is a mini red dot sighting system built to be tough and affordable for airsoft use. This comes with a picatinny rail adapter that can be removed and mounted directly to optic platforms that accept a Doctor style red dot sight footprint. This uses a single CR2032 battery and has a single button to turn it on or off and cycle through multiple brightness settings. This optic is made of metal yet is lightweight and works great for slide mounted applications, as an offset sight, or by itself on top of an airsoft gun where you would want a compact optic."
