For gunsmiths or firearm owners working on AK firearms, the Otis AK soft jaws are indispensable for protecting the firearm while securing it in a vise. They are compatible with a range of vises, from light-duty to large, heavy-duty models, with a minimum jaw measurement of 4 inches in length and 1/2 inches in height. Constructed from non-slip rubber material, these soft jaws offer an optimal balance of hardness to securely clamp even the smallest components, while maintaining the flexibility to conform to various firearm shapes. Softer than gun parts, they prevent marring or scratching of gun metals. The rubber is resistant to oil, solvents and alcohol and can be easily cleaned. Additionally, the soft jaws feature a top lip that not only protects the firearm but, when used with embedded magnets, also secures the soft jaws to the vise jaws. Designed by professional gunsmiths, these AK soft jaws are specifically tailored for AK firearm platforms, featuring detailed contouring and rivet holes to perfectly fit and securely hold AKM pattern rifles, the most prevalent AK style. Note that these soft jaws are not compatible with RPK pattern AK rifles.
