fed-ex it directly to charlie...he will give you the address. once completed, he will return the gun to you via fed-ex. he can send it to your home, or as he did for me, have it held at a fed-ex office for pick-up. in that case, use the address of the fed-ex office with a "hold for pick-up" line added.
it must be signed for, so if you wont be home, have it held at a fed-ex office for pick-up.
