An Army M-60 box is waterproof and incognito. You can go to a craft store and buy the firm foam to cut out and settle that baby like nothing better! I never carry my high-dollar pistols in the padded rugs they came with...just begs "steal me". So do high dollar cases.
Winchester makes a pistol sized case that is bothe very attractive and reasonbly secure with combo and keys. I have travelled with my AUG in one and love it. If you want to spend the bread get the Pelican. The cutouts are excellent and replaceable.
