Optic for .300 (subsonic to 250 yards)

[grey2112]

So, I'm getting my Whisper built and it will have two barrels - a 16" one for everyday use and for supersonic bullets, and a 9" one for special occasions and for subsonic only.

I'm considering optics, and would like to get some suggestions from you all. Money isn't a huge factor - I believe in "you get what you pay for" when it comes to optics. I own mostly Zeiss Conquest scopes.

Now, would I be doing myself a dis-service if I got anything higher in mag than a 6x? I was considering either a 1-4x or a 1.8-5.5x38 (Zeiss makes one in the Conquest line).

Any other good quality scopes out there that would serve my purposes? I'm looking for something with a fast acquisition at low mag, good light gathering, and up to a 6x magnification for precisions shots out to 250 yards (about the max effective range of a .300 Whisper subsonic with my suppressor).

Thanks!
