Beretta SFOU66001 VCI 13.5" Rust Corrosion Moisture Protecting Non-Abrading Stretch-Knit Fabric Gun Sock

The Beretta SFOU66001 VCI 13.5" Rust Corrosion Moisture Protecting Non-Abrading Stretch-Knit Fabric Gun Sock is purpose-built to shield firearms from the environmental threats that degrade metal and finish during storage and transport. The 13.5-inch length accommodates short-barreled rifles, carbines, and full-size handguns with accessories, making it a versatile protective sleeve for shooters who store multiple firearm types or move weapons between ranges, vehicles, and home safes.

VCI (Volatile Corrosion Inhibitor) technology embedded in the stretch-knit fabric actively releases rust preventatives that form an invisible protective layer on metal surfaces, eliminating the need for additional oil or grease applications. The non-abrading knit construction resists snagging on sights, optics, and finish—a critical consideration for precision rifles and firearms with mounted accessories. The elastic stretch design accommodates varying barrel profiles and stock configurations without slipping, and the soft interior fabric protects blued, stainless, and PVD-coated finishes equally well.

This gun sock addresses the specific corrosion challenges faced by shooters in humid climates, coastal environments with salt air, and those who store firearms in unheated spaces where condensation and moisture accumulation accelerate oxidation. Law enforcement armorers, military personnel, range operators, and private collectors rely on VCI sock solutions to extend finish lifespan and reduce maintenance intervals between shooting sessions. Unlike traditional soft cases or silicone-treated pouches, the VCI chemistry actively inhibits corrosion rather than simply creating a passive barrier.

Beretta's positioning of this protective accessory reflects industry-standard practice for long-term firearm storage. Gun socks represent an economical first line of defense, appropriate for ready-access storage where full hard cases are impractical, or as a secondary protective layer inside larger storage containers. The 13.5-inch specification fits the sweet spot between compact handgun protection and short-barreled rifle coverage, making it the most frequently deployed size in multi-firearm collections.
