Over promised and under delivered. - Vortex Crossfire II AO 4-16x50mm 30mm Tube Second Focal Plane Rifle Scope

I acquired a Vortex Crossfire II 4-16X50mm AO scope in used condition. I immediately noted multiple problems with it. The AO focus ring is marked for various yardages but the indicated yardage did not match with the actual distance to my target. This was regardless of the magnification used. In addition, at low and high magnification, there is a distinct "fish-eye" distortion on the edge of the viewing field that will add to eye fatigue. It's most notable when scanning across open fields. I sent the scope back to Vortex, and after inspecting it, they replaced it with a new one. Great customer service! However, the replacement scope had the same problems. I sent it back to Vortex and they said it was totally within their specs.

If the factory eliminated the yardage marks from the front focus ring, and limited the magnification to being between 6-12 power, it would be a fine product. But the factory stretched the specs to go for a 4-16 power scope and the optics just don't hold up. Do yourself a favor, for the price you can get something much better elsewhere.
