The original Mossberg JIC (Just In Case) cruiser shotgun comes with an airtight resealable PVC tube. The new JIC II, which will be sold alongside the original, comes in a soft case with shoulder strap. The 18.5″ Mossberg 500 shotgun is stored with the barrel and pistol grip removed. A tool is included in the pack to break it down and reassemble it.
This is not designed to be a when-things-go-bump-in-the-night gun, but rather a bug out bag. My recollection may be wrong, but I believe the pack has been designed to be compatible with Mossberg’s upcoming modular ASAP survival system.
