I can't believe this hasn't sold. I have an xrs2 and I did some more digging online and these appear to have the same glass as the xrs2. I did a short comparison between the xrs2, viper, razor, and Trijicon a couple weeks ago on here. The bushnell had the best glass and tracked perfectly. For under 2500, the bushnell is hard to beat. For 750 dollars, this should be a no brainer. Good luck grouse, can't believe you're having a hard time selling this
