Abstract: A modular armorer's stand has a block that, on one end, can engage the magazine well of a firearm frame. The other end of the block has a tongue that can be slid into a base. The base can be mounted to a surface such as a work bench. As such, the frame is held solidly in place for gunsmithing. The firearm's magazine release can engage a notch in the block. Each block can be sized specifically for a certain firearm or firearm family while every block has a tongue that can be held by the base. An armorer therefore needs a single solidly mounted base and that base can hold various blocks that, in turn, hold various firearms.
