Burying Guns & Ammo with MonoVault Burial Tubes

Best way to bury guns

Whenever the headlines carry news of a new law that limits our 2nd Amendment rights, conversations will often come around to the subject of burying guns or creating a survival cache of some sorts.  If not firearms, people talk about burying silver and gold, ammunition, cash, important documents, even caching food storage or fuel on the path to a bug out location.  I even know of people who bury gear at their bug out location in the event it is compromised before they reach it.

Burying Guns – The Law

While I know of no law that would prevent someone from stashing stacks of canned beans and birth certificates, one must be fully aware of the laws in his/her own locale when it comes to burying guns or ammunition. Take the state of Massachusetts, for example:  The law requires guns to be stored in a specific manner.  All guns, when not in use, with the exception of primitive firearms, must be stored or kept “secured in a locked container or equipped with a tamper-resistant mechanical lock or other safety device,” to prevent unauthorized use. Penalties are assessed even if no underage person obtains access (source).

I’m no lawyer, but it’d seem to me that you’d be violating the law if you’re burying guns in Massachusetts. So – stay mindful of the laws in your area if you’re seriously considering the subterranean storage of guns or ammunition. Even if you find it is legal – is it safe or wise to do so? ­What if a stranger discovers it? Could children? Those are questions for you to answer. Stay legal. Stay safe.

A Hidden Cache

Survival Cache Burial Vault

Guns, ammo, gear, precious metals, and most anything you deem necessary can be buried in a variety of different containers, the extent to which goes beyond the scope of this post. Here we’re focusing on one type of container, the Mono Vault.  The Mono Vault is a ready-to-bury storage tube. Constructed of a one-piece molded body, there are no joints along the sides or on the bottom that could leak.

This type of product represents the simplest, fastest, most convenient way to get your goods safely in the ground. Looking like a large PVC pipe with sealed ends, it functions in much the same way. While the tubes do not come cheap, once one goes about pricing similarly-sized PVC pipes, and factors in the value of one’s time, there’s a new appreciation and understanding of the pricing, and the product itself.

The tubes come in a variety of different sizes, and all function in the same manner, but for purposes of this post, we’ll be looking at three in particular: the 110s, 130s, and 248s. Each has similar construction, coming in either black or olive drab. The “s” denotes standard wall construction of 1/4”. The top of the containers have a large-mouth spin-on lid with o-ring seal, and atop that sits another cover, the “Burial Shield,” that looks much like the top of a landmine.

The 110s has an inside diameter of 9 3/4” and an inside depth of 7 1/2”. The 130s has a diameter of 9 3/4” and a depth of 23 3/8”. The Mono Vault 248 has a whopping diameter of 12 1/4” and a depth of 45”!  Dimensions, diameter, and depth – blah, blah, blah. The real question here is – how much stuff can you cram into these things?

MonoVault 248 Storage

Well, we found out.  This is the Mono Vault 248 with everything we crammed into it:

  1. A mid-length AR with collapsible stock, five 30-round magazines, and 1,075 rounds of 5.56,
  2. A Ruger 10/22 and 1,275 rounds of .22lr,
  3. A Remington 870 shotgun and eighty 12-gauge shotgun shells,
  4. A S&W Shield with spare magazine and 450 rounds of 9mm,
  5. A crank-powered radio,
  6. A Buckmaster knife,
  7. Small pair of binoculars,
  8. A small bag of various “survival” tools (fire-making products, few first aid products, etc.),
  9. Small solar panels for charging batteries, and
  10. #10 Can of Freeze Dried Food Storage.

Looking into the top with all of this gear, there’s still room for more. If we’d been more careful with the packing, made boxed ammo into loose ammo, we could have easily double the amount of ammo and packed another 45 servings of freeze dried chocolate drink.

Burying Your Mono Vault!

Bury your tube before filling it, or you may be carrying a very heavy tube.  The makers of the Mono Vault write:

Your Mono Vault will float. While this is great on the water, it is not so good in burial applications. Clay soils of an excavated hole can inhibit drainage of any water that may collect. Water collected in the hole can impart tremendous floating forces on your Mono Vault, driving it to the surface and then some. It is advisable to anchor your vault effectively with appropriate compaction or the addition of hardening or sealing agents. A few sacks of concrete in the clean bottom of your backfill can serve to anchor the vault to the bottom of the hole. Use caution with concrete in the vicinity of the lid as most concretes will shrink as they cure and may cause some distortion of the vault and critical sealing surfaces. Choose your site carefully to avoid natural drainages that may direct water to your vault. Slightly sloped or cresting locations may be best.

Surround the tube with crushed stone before back filling it could offer additional protection.  If you’re concerned about the possibility of someone hunting for your cache with a metal detector, you can always throw rusty, scrap metal (old nails, cans, etc.) around the site to help throw people off.

The manufacturer also writes:

In high frost areas where the ground freezes deeper than the cover soil, it may be advisable to cover your Mono Vault with a piece of foam insulation below the cover soil and extending a couple of feet out from the perimeter of the vault. This insulation can reduce freezing of the soils around the neck of the Mono Vault and the resulting pressures and possible distortion. Be aware that such insulation can also slow snow melt so don’t use a square piece that will leave an unnatural looking residual snow pile.

The landmine-looking Burial Shield will help direct water away from the lid, and it protects against possible shovel damage as it is being recovered. The shield will keep the lid area clear of dust and dirt that could otherwise enter the tube when you open it, potentially compromising the unit when it’s resealed.

How Are You Going To Mark Your Site?

Are you going to be able to find it when it’s time? You can identify the site by remembering natural landmarks, making note of them, or by using a portable GPS—just make sure you have good satellite reception. A 10’ difference could mean a whole lot of digging in search for it.  There are additional products you can buy to protect the contents.  “NoRust” storage bags are available for guns, and your standard desiccants will work wonders for sealing moisture out. If you’re feeling ambitious, you could always use cosmoline on your guns.  And remember—never whisper about the location of your cache!  What would YOU bury? How would you bury it?  I welcome your comments.
