Can I ask on which rifle and what would be the typical usage? I'm just curious on which application is needed to have $2000 scope :-)
Anybody who wants a high quality optic on their rifle.
A different way to ask your question is what are some of the advantages of the razor over other scopes in their series:
Better glass. This will lead to clearer images especially at dusk and dawn
Large objective diameter. More light. This provides benefits in low light situations
Turrets. Mil or Moa allow for precise dialing for increased accuracy
Build quality. Designed to take a bump or two
Most people buying high dollar scopes to tend shoot longer distances and change distances frequently. Generally competition shooters but some hunters use them too
