Scopes can fail... but all you need to do is spend some time on various message boards and it seems that some of the Vortex lines fail more than other brands (not including crap like BSA, Scorpion, ZOS, etc). I would expect that from the Crossfire and Diamondback lines, but the Viper PST line can cost anywhere from $700 to $1000, so one would hope they'd be a little more durable. My PST had a defect right out of the box, so it was exchanged on warranty for a brand new one that I immediately sold.. and not just because I had a problem with the first one, the glass just wasn't to my liking. Vortex has an amazing warranty (something that i've stated on this site before most people even heard of the brand), but it is built into the price of the product.
