The dot on mine frequently "washed out" when shooting against bright/snowy targets. Still, you can get around that by taping over the front lens and using both eyes.
Mine was a first generation, so they're probably better now...

Dmitri, I think it might be the rail/mount. I just took my 11.8" vz out with the same rail, cz mount last weekend, and my aimpoint was adjusted to close to the extreme too. That was at 100m.
