As i am in america i bought these for my real not airsoft ruger 556, and they work great and spot on right out of the box, that being said if they work for a real rifle not sure how well they will work for airsoft or if that is even a factor as i dont play airsoft lol, if i had one compliant it is that the flip up spring is a little to stiff, so you have to press fairly hard and if your not careful the fiber optics will pinch you badly
