The Tipton 1911 Mag Well Vise Block is possibly the handiest tool a 1911 owner could ask for. Designed for use with the Tipton Best Gun Vise, this center support slides into the magazine well and provides a steady base for cleaning or light gunsmithing on your 1911. Center section rotates 180 degrees. Users without a Best Gun Vise can mount the Mag Well Vise Block directly to their bench top with the included fasteners. Built in Barrel Bushing wrench.
