Just a comment from an old fart. Folks on here think nothing about dropping 3-4,000 K on a scope. A few years ago I thought a $800 Leopold was a bfd. And then I bought a $1700 on a Swarovski hunting scope 12 years ago and thought man o man that's a lot of money. Now I have Nightforces, Sightron and a couple of Kahles. Back in the $800 scope days if I had bought a $1500 scope and it was not perfect I would have been seriously BENT. Not to presume anything about the OP but I can understand his concerns about a flaw on a new, not cheap scope, same as I understand how guys here are nonplussed about oil drops in the scope and sticky turrets on their new $3,00K+ scopes.
He should just send the pic to Nightforce customer service and ask them about it. Pretty sure they would reassure him so he could get back to using the scope for some shooting.
Cheers!
