VCI M4 Rifle Bag for Compact Rifle and SBR Storage
The API VCI M4 Rifle Bag is a 14" x 36" anti rust firearm storage bag for compact rifle platforms.
It is ideal for M4-style rifles, AR pistols, SBRs, and compact rifles with barrels shorter than 16".
This compact VCI rifle bag was designed to give the U.S. Air Force a better fitting firearm storage bag for armory weapon racks.
The shorter 14" x 36" size helps reduce excess material while still protecting compact rifle platforms from rust during storage.
Made in the USA by Arms Preservation Inc., this bag is built for clean, reusable, and long-term firearm rust prevention.
Why API Makes One of the Best VCI M4 Rifle Bags
- Compact rifle fit: 14" x 36" outside dimensions fit many M4-style rifles, AR pistols, and SBR platforms.
- Designed for shorter barrels: Ideal for compact rifles with barrels shorter than 16".
- Armory rack friendly: Designed around military armory storage needs and reduced excess bag length.
- 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.
- Reusable closure: Hook-and-loop closure allows fast access and resealing.
- Optic-friendly storage: Designed for many compact rifles with red dots, optics, lights, and accessories.
Made with Cortec VpCI-126 MIL VCI Film
API uses Cortec VpCI-126 MIL film on the inside layer of this VCI M4 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 during long-term packaging and storage.
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 M4 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 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.
Built for M4-Style Rifles, AR Pistols, and SBR Platforms
This 14" x 36" VCI M4 rifle bag is sized for compact modern firearm platforms.
It is a strong option when a full-size rifle bag creates too much excess material.
The compact size works well for many collapsed stock, folded stock, and short-barreled rifle configurations.
It also helps armorers store compatible firearms more efficiently in racks, safes, cases, and storage rooms.
Common fit applications
- M4-style rifles
- AR pistols
- Short-barreled rifles
- Compact tactical rifles
- Rifles with barrels shorter than 16"
- Collapsed stock rifle configurations
- Folded stock rifle configurations
- Many compact rifles with optics, red dots, lights, and accessories
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 M4 Rifle Bag gives firearm owners and armorers a cleaner 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.
That moisture can reduce storage performance and create a risk of surface rust.
How to Use the API VCI M4 Rifle Bag
- Confirm the firearm is unloaded.
- Clean and dry the firearm before storage.
- Collapse or fold the stock when needed for proper fit.
- Place the firearm 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.
