For gunsmiths or firearm owners working on their firearms, the Otis Flat Soft Jaws are an essential item to protect your firearm while keeping it secure in a vise. Works with light duty vises up to large, heavy duty vises (minimum vise jaw measurement is 4inchL x 0.5inchH). Composed of a non-slip rubber material, these soft jaws have the perfect balance of hardness to keep even the smallest parts clamped and flexibility to mold to the various shapes of a firearm. Softer than gun parts, these soft jaws will not mar or scratch gun metals. The rubber is oil, solvent and alcohol resistant and easily wipes clean. They also feature a top lip which not only help protect the firearm but in conjunction with embedded magnets, also hold the Soft Jaws to the jaws of the vise. Designed by a group of professional gunsmiths, the flat soft jaws are recommended for use with a wide array of firearm parts. A large, flat surface allows the firearm owner or gunsmith to clamp large flat objects such as firearm receivers with total security.
