Used 1.5-6x42 helia csx on my combination gun in 7x65r and 12ga.A friend of mine now has the same model mounted on his blaser r93 9.3x62 rifle.Superb rifle scope. In the same league with zeiss ,swaro and schmidt und bender. If you are thinking about buying an Kahles scope my advice is - Don`t hesitate and do it.
One more word of advice - Go for a model with rail mount(a true european classic)and an illuminated reticle.

p.s. Kahles is one of the first optics companies to start building rifle scopes.
Some years ago some Austrian found in the austrian alps an 90+ year old kahles scope burried in the snow.It was in mint condition.I was told that this scope is now in the Kahles factory museum.
