How VCI Gun Bags Work

How VCI Technology Works to Protect Firearms from Rust

Arms Preservation Inc. – Multi-Layer Vapor Corrosion Inhibitor Protection

Understanding VCI Firearm Storage Technology

VCI (Vapor Corrosion Inhibitor) technology is the same proven corrosion-prevention method trusted by the U.S. military, defense contractors, and industrial manufacturers worldwide. Arms Preservation Inc. adapts this technology into multi-layer firearm storage bags that provide 5+ years of rust prevention—without oils, greases, or messy coatings.

The Science Behind VCI

VCI Molecule Release – The interior lining of our bags emits invisible vapor corrosion inhibitor molecules.
Molecular Bonding – These molecules coat all exposed metal surfaces, creating a protective barrier that blocks moisture, oxygen, and contaminants.
Complete Coverage – Protection reaches every part of the firearm, including hard-to-reach internals like chambers, bores, and firing mechanisms.
Safe Dissipation – When removed from the bag, VCI molecules naturally dissipate within minutes, leaving the firearm ready for immediate use—no cleaning required.

Why Multi-Layer Matters

Unlike single-layer polyethylene VCI bags, our multi-layer barrier system combines:

VCI-Infused Interior Layer – Releases consistent protection over years.
Moisture & Oxygen Barrier Layer – Blocks environmental contaminants.
Reinforced Outer Layer – 8 mil combined thickness resists tears, punctures, and handling damage.

FAQ: How long does the VCI last?
Our multi-layer VCI bags protect for 5+ years, depending on frequency of opening and storage environment.

How VCI Compares to Other Rust Prevention Methods

Method	Protects Internal Surfaces	Mess-Free	Long-Term Protection
