Moisture beware! Browning’s VCI (Vapor Corrosion Inhibitor) Gun Sock seals out moisture, providing full protection by forming an enclosure around your firearm from muzzle to butt. VCI penetrates into the smallest crevices where oils cannot reach, driving out moisture. The “safe” solution, the VCI Gun Sock, when used in a safe or cabinet, will offer additional protection to all metal items in the enclosed area. The black gun sock fits most firearms and has a drawstring closure to secure your firearm inside.
