Silent Dry Shotgun Cartridge Vaportack (12g). Ensure long-term protection for your 12-gauge shotgun and its barrel with the VAPORTACK 12 GA anti-rust cartridge. Engineered to match the size of a real shotgun shell (1:1 scale), this device fits directly into the barrel or can be placed in your gun safe, case, or storage box. Using V.C.I. (Volatile Corrosion Inhibitor) coating technology, it releases microscopic corrosion-inhibiting molecules that form an invisible protective layer over metal surfaces—guarding against rust, moisture, and oxidation.

This product is ideal for shooters, hunters, and firearms collectors who want continuous, passive protection without messy oils or coatings. The ABS/PC shell encases microcrystalline cellulose imbued with VCI compounds, balancing function and form. Place it in your barrel or storage and forget it—until its time to replace or recharge.
