Abstract
A firearm based breeching tool uses the expansion gases of a blank high capacity firearm round to fire a piston at a breeching chisel, the chisel having a cutting head that is designed to breech a hardened obstacle. The invention is based on an assault rifle configuration that is modified to use the pump action of a shotgun to replenish a round of ammunition into the firing chamber and otherwise reset the device including the firing piston and the standard trigger mechanism.
