I think this is great. It works as it should and is easily adjustable and I use it all the time on my M4. Only problem I have with it is the fact that the rubber cover that comes with it was all twisted and wouldn't fit cos of this but It is an "extra" that you get with it not that important or vital to the function so overall really good affordable tool from G&G!

Really disapointed in this sight. When used inside with either green or red, the graphic is ghosty even on its lowest setting. On its highest setting it can't be seen on a bright day. There is a massive amount of reflection.
The rubber flip up covers do not stay closed, this is because the rubber is too durable and a really bad fit. Considering this scope is just under £55 and made by G&G I really expected a lot more. I have a G&G 1x30 Aimpoint Replica with Flip-Up Covers sight on my other gun and that is absolutely fantastic. I think I'll be getting a second one to replace this as soon as possible. The only reason I give it a value of 2 is because it appears to be built solid and it looks good.
