I had 2 Crossfires returned for warranty exchange because they wouldn't hold zero. I sold the third one before I even bothered mounting it. It's a $50 scope with a $200 warranty.
Save yourself some headache and time. Wait until you find a sale on a Bushnell Elite 3200. You won't regret it. I have 2, one on a 7mm Rem Mag and one on my 10/22. I paid less than $300 for each of them.
If you insist on a Vortex, save some money and step up to at least the Viper line. It just *might* last half as long as an Elite 3200...if you're lucky
