So I ended up with one of these years ago actually picked it up on eBay and when I got it I seen her as like a little teardrop on a dust inside it contacted Zeiss and sent it to him they sent it back to me told me it was a fake I got on with eBay and prove that it was a fake I had to send it back to the original seller it got sent back to me and I got my money back through eBay on it I had issues that on a 243. You may get it to work good on something I put it on a gun and try it but I wouldn't go through more than 10 rounds to 20 rounds. I would quit if it's not holding zero for you
