Sadly, I am unable to give you any information on the exact credit requirements you would need in order to have a chance at being approved for one of their cards. What you should keep in mind is the fact that your credit score is not the only thing credit issuers will judge you on when determining whether or not you should be approved for a card. Unfortunately, your credit score does play a very important role in determining your approval. To answer your other question, I don’t believe being a member of the NRA will have any impact on your chances of being approved. I don’t believe you are even required to join NRA in order to get this card.
