Abstract
An obturator ring (4) for a mortar round (2) is proposed where the geometry of the ring (4) is modified by its sliding and striking stationary anvil (18) when the round (2) is placed in the muzzle-loaded mortar's barrel (6) and reaches its bottom. The initial ring (4) geometry does not impede round's travel down the barrel (6) while its modified geometry provides a gas seal between the round (2) and the barrel (6) wall.
