Edward also does a very nice red/green dot sight with a single circular lens for £19.95. It fits 11mm dovetail or weaver. It is not listed on the website but it is illustrated in the JSR advert in gunmart and AGW. If you just ring Edward and ask for the £19.95 red/green dot sight he'll find it. Available in black or silver. Mine arrived a couple of days ago but I haven't got around to fitting it yet, perhaps at the weekend.
Just looked on the box, its an NcStar, made in China for the American market.
