There have been rifle scopes already developed using this "laser bending" technology and have been around for a few years now, but not to the general public, just the military. The information says that they are poor at reading wind deflection under 500 meters, OK to a 1000 and beyond.
There is currently a number of companies looking to bring out a civilian rifle scope version, but since i first heard of this some years back, nothing has shown up.
The technology they all use is as a range finder does, but have a built in sensor that reads the deflection of the returning beam.
Have a read of this link, it may change your view on this equipment for now. The next generation may be something to look forward to.
