Small Arms: Good Prep Protects Your Weapon for Shipping

There have been some questions from the field about shipping weapons. Here’s what you need to know for your weapons to arrive at their destination ready for use:
The first step is to make sure the weapons are thoroughly cleaned before packing them for shipment. Always follow the cleaning instructions in the -10 TM and don’t ever steam clean weapons!
Make sure to use a generous amount of CLP on the inside and outside of all weapons except the MK19. Check out the table below for the MK19’s lubricant.
Never use bubble wrap! Bubble wrap traps in moisture and can cause corrosion.

Use volatile corrosion inhibitor (VCI) barrier paper to wrap each weapon. One side of the barrier paper has a coating that helps keep the lubricant in. Place the weapon on this side and then just fold the barrier paper and tape the seams. The barrier can also be heat sealed but it’s not necessary. You can also goose neck (pull the ends together and twist) the barrier and tie it off.
Place the wrapped weapons in the box. If the weapons need to be layered, put at least one sheet of greaseproof paper between each layer. The best way to layer is to sandwich a sheet of corrugated fiberboard between two sheets of greaseproof paper. Make sure there’s no room for the weapons to shift during transport. Finally, add a desiccant pouch to the weather-resistant fiberboard box or hard container. 

Here are the materials you’ll need:
