For gunsmiths and firearm owners, OTIS Soft Vise Jaws protect firearms while keeping them secure in a vise. Composed of a non-slip rubber material, they offer the balance of firmness and flexibility to hold small parts and conform to various firearm shapes without marring metal surfaces. Embedded magnets and a top lip hold the soft jaws to the jaws of the vise for stable clamping; the rubber is oil, solvent and alcohol resistant and easily wipes clean. Designed by professional gunsmiths, these soft jaws work with light-duty up to large heavy-duty vises (minimum vise jaw measurement is 4L x 0.5H) and are recommended for clamping receivers, slides and a wide array of firearm parts during gunsmithing and firearm work.
