Before I even post this, I will admit that I should have known better. I bought this scope and went to sight it in and the glass is just dreadful. I made every adjustment that I thought appropriate and had another set of eyes do the same, and even at the $399 price point it is not something I can use. I bought it from Camera Land (NY) and they were great and asked me to send it back to Athlon. According to my tracking number, Athlon had it in their hands for less than two hours before letting me know that the glass met their standards, tracked just fine, and it was on it's way back. I did not expect a high end scope, but I would think my glass should be sharp enough to see my groups at 100 yards at 10x or 12x. As I said, I knew the risk and lost out. Learn from my mistake. I have had nothing but good luck with the SWFA SS scopes I bought at the same price point, so I rolled the dice on this Athlon and crapped out..
