The TiptonA(R) 1911 Mag Well Vise Block is quite possibly the handiest tool a 1911 owner could ask for. Designed for use with the TiptonA(R) Best Gun Vise(TM), this center support slides into the magazine well and provides a steady base for cleaning or light gunsmithing on your 1911. Users without a Best Gun Vise can mount the Mag Well Vise Block directly to their bench top with the included fasteners. Loaded with handy features, this tool is a must have for anyone with a 1911.
