Not Quite Up to Date

[Mortblanc]

For "long term preps" I would be working your system to the limits.

Parts available and ready for assembly, but all perfectly legal, separate and unrecognizable with the lock making an excellent decorative paperweight.

Just as a hint, our manufacturers make their barrel stock from premanufactured high pressure hydraulic tubing. They ream the ID and mill the outside as needed.

A chunk of raw hydraulic tubing in the rafters of the shed is just that, but ready to be something else. Mixed with a couple of random lengths of galvanized or black pipe it is just left over plumbing.
