I was thinking the same thing. I just dont think I will put it in a plastic bag. I have never had water leak into the tool box. Even if my gun gets stolen out of my tool box it is just a SKS so it wont be a big loss. I really like my SKS's though so I was kinda thinking about using a Nagant. I would have to buy another type of ammo but those guns go for 80 at Aimsurplus.com
