The secret to storing guns properly, is to pull them out every 2 weeks to 30 days, and re-oil them. DON'T let them go months without checking them. :shake: :thumbsup:
The only good alternatives are: to use oiled paper and protective greases to coat and protect the guns during long term storage; and, if you have access to the New Vacuum machines and those long bags they have, you can put a well-oiled gun inside a plastic bag, then suck all the air out( and moisture) with that machine, and seal the bag around the gun.
If you put a couple of dessicant packs inside the bag with the gun, you will insure dry storage for as long as the plastic bag lasts.I would still have someone check the guns monthly to see that they are still sealed in plastic, or that nothing had damaged or destroyed whatever packing box, crate, or safe you store them in.
FWIW, if I am going to be storing a gun someplace other than where I live, and sleep each night, I like to remove a key part of the gun so if stolen, it can't be fired. On MLers, I remove the locks and store them separate from the stock and barrels.
On modern guns, I remove the bolts, or breechblocks, and store them separately.
Even if a thief might know what is the proper breechblock, or lock, for a particular gun, and discovers both locations of storage, it would be rather rare for a thief to know how to put them back in the gun correctly to get the gun to fire. ( They are not that well-educated, contrary to what you see in movies and on TV.)
Unless a gun will fire, its less than useless on the black market, BTW. Thieves steal guns because they generate the highest income that will buy them drugs. They still are getting only 5 cents on the dollar in value, and sometimes a lot less. Unless the gun works, they get nothing.
