Well, that's sort of implied by "If you're going to buy Chinese ..."
OTOH, Vortex makes military and police optics for their army and LE. They seem to hold up well. Not sure this is from their "commercial" division ... I looked into becoming a Vortex Distributer. I got a look at teir high end optics.
The turn off was by the time you get to their world class stuff, it was nearly as expensive as ours or the Euro's... In some case a tad heavier the Leupold, not coated as well a Bushnell Elite for wet weather work, and the exit pupil was more constrained ... So I passed.
If it was on the shelf and I was assembling a rifle, I might grab a Vortex, depending on what else was available ...
