No I haven't. We just got a new retailer in town that carries every scope and mount that NightForce makes. I'm sure at some point I'll go have a look at them. Of course wont be able to do a full proper evaluation, just perhaps comment on the initial impression. I have looked through NXS quite a few times during varying lighting conditions in the field. Nice glass but nothing that gets me excited. In reading reviews and opinions, all the NF loyalists who own the new ATACR and BEAST seem to all say the glass is a big improvement over the NXS.
