Finally got the email. I ended up getting in touch with a travel agent who was kind enough to help me out. He couldn't contact them on my behalf because I purchased the ticket, but he told me they usually will not do anything with the firearms email prior to 14 days out from your flight. He also gave me the email address that they use, which was different from the one the Qatar rep gave me over the phone. I emailed them last night, yesterday was 14 days out, and I received an email back from them this morning stating they would forward it through to thier airport staff and there was a list of all their rules and regulations and subject to final inspection I should be good to go. I guess they will have the firearms surrender form there at the place of inspection.
