ABSTRACT:
The improved mortar has a sealing means that provides a double seal to the firing pin so that hot ignition gases from the mortar tube are prevented from damaging the firing mechanism. The improved mortar also has an improved base plate, the improvement in the base plate being an even number of radial ridges that extend radially from the base plate and are arranged in equal angles at the center. Every other radial ridge is forked and the branches of the forked radial ridges are parallel to the adjacent non-forked radial ridges.
