I have the opportunity to buy a 6X Burris Compact with AO for $179. The scope was a blemish from the factory, and was being sold at this price. It seemed like a good deal, since I was wanting a scope with AO. It has a cosmetic flaw (minor scratch), but nothing major I see that would keep me from wanting to buy the scope. Does this sound like a good deal? Is there any danger in buying a factory blemished scope? I would like input.
