For makes no difference £20 this sight is great. You are getting a full metal red dot sight that, in my opinion, is better looking than all the others available. The aim point style red dot has to much frontage and is to short to look good on anything other than a pdw weapon. The length and the swepping curve into the smaller window make it better looking. While the bracket does not engage with the slots in ris rails, it still grips firm and has the added bonus of fitting nicely on the SA80 dovetail rail without modification. Well worth buying especially in tan.
