Little scratch won't hurt. Don't worry about it. It's a big aperture. Enjoy the scope.
It's like when you get a brand new car with shiny metallic paint. The first spec of dust on it irritates you then one day your 5 year old kid learning how to ride his new bicycle for xmas makes a 1m long gash on the side doors with his brake handle ... and you have another beer.
Life goes on.
