Shop around and you can find some good scopes. I do have a good red dot from Hong Kong but its sight and mount in one that I find too low when using full face. But the view is good and again its taken a kicking and still works. Try places like airsoft club, they quite often have a couple of sights that look exactly the same but one cost £35ish and the other costs over a £100 the dearer one can be quite good but it is a gamble. I have binned more red dots than any other airsoft accessory.
