G&G GT1 Red Dot Sight w/ High or Low Mount. A fantastic low profile sight!  Includes battery.  Great for use with a facemask, as it is naturally raised higher on the top rail of your gun.  Very popular and a solid scope option. G-12-025 (low mount) and G-12-025-1 (high mount).  Real steel quality for airsoft use.  Can be used with riser mounts also.
