I highly recommend Pelican. We used them extensively when I was military-never saw one break and they saw rough treatment. They are airtight with a purge valve and do a great job of keeping out the ultra fine dust of the desert. I bought one for myself and have been very pleased. Its been all over the US and up to Northern Quebec on float planes and twin otters two times. Each time I arrived with an undamaged gun that was still sighted in.
