Military Weapon VCI Storage Bags:
Proven, Reusable Protection for Rifles, Pistols, and Ammunition
When weapons are parked in racks, armories, or long-term storage, corrosion is the enemy. Arms Preservation Inc. (API) Military Weapon Storage Bags combine a robust exterior barrier with an internal Vapor Corrosion Inhibitor (VCI) layer to protect firearms, parts, and ammunition for 5+ years (depending on use)—without messy oils or greases.
Why VCI Weapon Storage Beats Traditional Methods
-
Dry, residue-free protection: VCI molecules form an invisible, non-oily protective layer on metal surfaces—safe for all metals, finishes, stocks, optics, primers, and electronics.
-
Reusable closures & faster workflows: Bags open/close quickly and can be reused, delivering meaningful labor and material savings versus multi-step, heat-seal preservation processes.
-
Long-term performance: API’s multi-layer design provides durable corrosion prevention for at least 5 years or more (depending on use).
Field-Tested to Military Requirements
API’s storage bag design draws on concepts evaluated during a U.S. Marine Corps effort (“M16 Long-Term Rifle Storage & Preservation Bags,” DLA Reference-Number-60033076) with testing at USAMC LOGSA PSCC (Tobyhanna, PA). Samples endured extreme cold, thermal shock, high-temperature and high-humidity cycling, drop and vibration tests, with results noting no detectable rust or condensation and performance equal to or better than a MIL-PRF-131 + MIL-PRF-3420 setup. Notably, packaging productivity improved from ~3 rifles/hour to 4–6 rifles/minute in that evaluation.
Simplify Compliance & Reduce Equipment Needs
Switching to API’s resealable bags can streamline preservation versus legacy guidance (e.g., methods referenced in MCO 4030.16F Section 5 for small arms). Because our bags arrive professionally heat-sealed on the manufacturing line, units don’t need to own or maintain heat-sealers for every closure—further cutting training, time, and consumables.

How VCI Works (Quick Explainer)
Inside each API bag, the VCI layer releases protective vapor molecules that bond to clean metal surfaces, blocking moisture and oxygen. Because the protection is dry and molecular, it won’t gum up actions or optics and is safe for primer-sensitive ammunition components.
Made in the USA
API designs and manufactures in the United States to maintain quality, consistency, and supply reliability for defense, law-enforcement, and professional users.
Frequently Asked Questions
How long do the bags protect?
With typical use, you can expect 5+ years of corrosion protection, and often longer depending on handling and storage environment. For maximum performance, start with a clean, dry weapon and close the bag fully.
Are the bags safe for optics, electronics, and finishes?
Yes. The dry VCI approach leaves no residues and is compatible with optics, electronics, primers, and common firearm finishes—no oils required.
Do we still need a heat-sealer?
No. API’s resealable design eliminates the need to purchase and maintain heat-sealers for routine armory work—reducing training time and consumables.
