Made with Cortec VpCI-126 MIL VCI Film

API uses Cortec VpCI-126 MIL film on the inside layer of this Muzzleloader VCI Bag.

This MIL version of Cortec VpCI-126 is a transparent blue VCI film designed for long-term corrosion-inhibiting packaging.

Cortec VpCI-126 MIL is qualified to MIL-PRF-22019D Type 1 and confirmed by the Naval Air Warfare Center Aircraft Division.

It is referenced with Qualified Product Listing QPL 13600 Ser 43500B120-3/531.

This widely used, military-approved VCI film helps protect ferrous and non-ferrous metals.

Additional standards and references include TO 1-1-686, TM 55-1500-331-34, NAVAIR 15-01-4, and NACE Standard RP0487-2000.

How This Muzzleloader VCI Bag Works

VCI stands for Vapor Corrosion Inhibitor.

Inside the sealed bag, the VCI layer releases corrosion-inhibiting molecules into the enclosed air space around the firearm.

These molecules settle on exposed metal surfaces and help reduce oxidation before rust starts.

This protection can reach visible metal surfaces and hard-to-reach internal firearm areas.

The outer barrier layer helps reduce exposure to moisture, oxygen, and outside contaminants.

Cleaner Than Heavy Oil, Grease, and Gun Socks

Many firearm owners use heavy oil, grease, desiccants, or gun socks for rust prevention.

The API Muzzleloader VCI Bag gives firearm owners a cleaner and more controlled storage option.

Place a clean, dry firearm directly into the bag and seal the hook-and-loop closure completely.

Do not store the firearm inside a gun sock while it is sealed in the VCI bag.

Soft gun socks can retain moisture and may create a risk of surface rust.

How to Use the API Muzzleloader VCI Bag

1. Confirm the firearm is unloaded.
2. Clean and dry the firearm before storage.
3. Place the firearm directly into the VCI bag.
4. Do not use a gun sock inside the bag.
5. Seal the hook-and-loop closure completely.
6. Store the sealed bag in a stable indoor location.
