The optic quality is really good, but before I close the deal on this does anyone have any input regarding parallax since there isn't an adjustment?

It's realistically going to be 400 yards and closer.

I've got a za3 3-9x50. I'd say it has a small amount. From what I hear minox is trying hard to keep the reputation up...if you get one you deem excessive I bet they'll fix it for you. I've sent scopes to Burris, leupold and Bushnell and all have fixed paralax for free.
