The first gun sock designed for the transport and storage of firearms under wet field conditions. Unlike silicone-based gun socks, the Beretta VCI (Vapor Corrosion Inhibitor) gun sock does not trap moisture. Instead, it uses VCI technology to form a protective chemical barrier that stops rust and corrosion from occurring, and works so well the sock is perfect for long-term storage. The sock is made of soft spun yarns that will not abrade metal finishes. Length: 13.5 inches.
