Made in the USA by Arms Preservation Inc., this rifle storage bag is built for clean, reusable, and dependable rust prevention. Why API Makes One of the Best VCI Rifle Bags Modern rifle fit: 14" x 49" outside dimensions fit many ARs, M4s, AKs, and tactical rifles. 16" and longer barrels: Designed for many modern rifle platforms with 16" or longer barrels. 5-10 year protection: Built for long-term firearm rust prevention when used correctly. 8 mil multi-layer design: Combines barrier protection with VCI corrosion protection. Cortec VpCI-126 MIL film: Uses military-grade VCI film on the inside layer. Low-MVTR barrier layer: The transparent MIL-PRF-22191F Type 1 outer layer has a low moisture vapor transmission rate (about 0.010 g/100 in²/day) to help keep the sealed air dry. Reusable closure: Hook-and-loop closure allows fast access and resealing. Optic-friendly storage: Designed for rifles with many optics, red dots, lights, and accessories. Made in USA: Built for gun owners, collectors, armorers, and professional firearm storage. Made with Cortec VpCI-126 MIL VCI Film API uses Cortec VpCI-126 MIL film on the inside layer of this VCI rifle 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 military-approved VCI film protects 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 VCI Rifle 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 rifle. 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. Learn how VCI gun bags work. Low-MVTR Barrier Layer for Stronger Moisture Protection This rifle bag's transparent outer layer is a MIL-PRF-22191F Type 1 barrier material. Its job is to slow how much outside moisture can reach your firearm. That barrier performance is measured by MVTR, or moisture vapor transmission rate, the amount of water vapor that passes through the film over a set area and time. A lower MVTR means a drier sealed environment inside the bag. The MIL-PRF-22191F Type 1 barrier used in this rifle bag has an MVTR of about 0.010 g/100 in²/day. A typical single-layer 4-mil VCI poly bag is around 0.06 g/100 in²/day. That makes this barrier roughly 6 times more resistant to moisture vapor. Material MVTR (g/100 in²/day) — lower is better Relative moisture protection API transparent barrier (MIL-PRF-22191F Type 1) 0.010 ~6× lower Typical single-layer 4-mil VCI poly 0.06 Baseline These values are typical published lab figures, not guaranteed specifications. The API barrier is measured under a demanding 90% relative humidity at 104°F (40°C), while many single-layer poly films are rated at 73°F (23°C). Because higher temperature increases vapor transmission, the real-world moisture gap is often even larger than these numbers suggest. A lower MVTR also helps hold VCI vapor inside the bag, so the Cortec VpCI-126 MIL film works in a low-moisture environment and supports long-term protection for both ferrous and non-ferrous metals. Built for ARs, M4s, AKs, and Tactical Rifles This 14" x 49" VCI rifle bag is sized for many modern rifle platforms. It is a strong fit for firearm owners who need more room than a compact M4 bag provides. The longer profile works well for many rifles with 16" and longer barrels. It can also fit many rifle setups with mounted optics or accessories. Common fit applications AR-platform rifles M4-style rifles AK-platform rifles Tactical rifles Modern sporting rifles Rifles with 16" and longer barrels Many rifles with optics, red dots, lights, and accessories Long guns stored in safes, racks, closets, cases, or armories Cleaner Than Heavy Oil, Grease, and Gun Socks Many gun owners rely on heavy oil, grease, desiccants, or gun socks for rust prevention. The API VCI Rifle Bag gives firearm owners a cleaner and more controlled storage option. Place a clean, dry rifle directly into the bag and seal the hook-and-loop closure completely. Do not store the rifle inside a gun sock while it is sealed in the VCI bag. Soft gun socks can retain moisture. That moisture can reduce storage performance and create a risk of surface rust. How to Use the API VCI Rifle Bag Confirm the rifle is unloaded. Clean and dry the firearm before storage. Place the rifle directly into the VCI bag. Do not use a gun sock inside the bag. Seal the hook-and-loop closure completely. Store the sealed bag in a stable indoor location. Read the full VCI storage bag instructions.

API VCI Gun Bags are made with Cortec VpCI-126 MIL film on the inside layer. This transparent blue VCI film is qualified to MIL-PRF-22019D Type 1. It is referenced with Naval Air Warfare Center Aircraft Division QPL listing 43500B120-3/531. API bags combine this military-grade VCI film with an 8 mil multi-layer bag design, reusable closure, and long-term firearm rust prevention. How long does this VCI rifle bag protect firearms? When used correctly, this API VCI rifle bag provides 5-10 year firearm rust prevention. Actual performance depends on storage conditions, firearm condition, and how often the bag is opened. What rifles fit in the API VCI Rifle Bag? This 14" x 49" VCI rifle bag fits many ARs, M4s, AKs, tactical rifles, and modern rifle platforms. It is ideal for many rifles with barrel lengths of 16" and longer. Is this VCI rifle bag safe for optics and accessories? Yes. API VCI Gun Bags are designed for firearm storage with many optics, red dots, lights, polymer parts, and standard firearm finishes. Can I keep my rifle in a gun sock inside the VCI bag? No. Place the clean and dry rifle directly into the VCI bag. Gun socks can retain moisture and may create a risk of surface rust during storage. Does this VCI rifle bag need to be heat sealed? No. The reusable hook-and-loop closure is designed for normal storage use. Heat sealing may be used only when a permanent seal is required. What makes API different from basic single-layer VCI bags? API bags use an 8 mil multi-layer design with a barrier layer and a Cortec VpCI-126 MIL inside layer. Basic single-layer VCI bags may not provide the same barrier strength, durability, or reusable closure design. What is the MVTR of this VCI rifle bag? The transparent outer barrier layer (MIL-PRF-22191F Type 1) has a moisture vapor transmission rate (MVTR) of about 0.010 g/100 in²/day. That is roughly 6 times lower than a typical single-layer 4-mil VCI poly bag, which is around 0.06. A lower MVTR means less water vapor reaches the firearm during long-term storage. API's barrier figure is measured at 90% relative humidity and 104°F (40°C), a more demanding condition than many single-layer films are rated at. Show more
