I am currently planning on purchasing a CMP Garand as a present to myself before leaving for Coast Guard Boot Camp on JAN18. However, I am not currently affiliated with a CMP organization. Is there a way to join an organization while at the North Store? Or is there an organization that I am able to join online and get some form of proof that I am affiliated with them in order to satisfy the CMP requirement? I would wait until I am active duty to purchase the rifle, but I would prefer to pick it out in person instead of ordering blindly through the mail.
