Laser range finding scopes compared
Shooting times (UK) has a comparison of three range finding scopes: the Bushnell Yardage Pro, Burris Laser Scope and Zeiss Diarange.

Whether the Zeiss is worth twice as much as the other two models is a matter of how much extra you are willing to pay for optical perfection and an illuminated reticule.
Both the Burris and the Bushnell offer good value considering their versatility, but my choice would be the Burris due to the sunshade and understated Ballistic Plex reticule system.
However, I did discover that when the temperature dropped to -6ºC both the Burris and Bushnell lasers stopped working, while the Zeiss worked perfectly.
This may be your deciding factor – quality will out.

I am trying to decide on what scopes to buy form y 223/5.56 and 7.62 carbines. I was considering the NcStar 4×32 mark III IR Tactical scope for the 223 because it is calibrated (say so anyway) for a 223.

I was considering the EOTECH 512-C for the 7.62 but am not sure if it would be better to go with a scope instead of a holo. What is your advice?
