a mandrel having an upper portion and a lower portion;
a barrel piston having a first end and a second end, and wherein the barrel piston extends over at least a portion of the mandrel when in an in-line configuration and releasably coupled in a relative position to the mandrel when in the in-line configuration;
wherein the mandrel has a first end on the upper portion and a second end on the lower portion;
wherein the mandrel includes an interior combustion chamber having a first end proximate to the first end of the mandrel and having an interior upper portion;
a pressure bulkhead disposed in the mandrel at the first end of the mandrel in the interior upper portion of the mandrel;
a pressure igniter coupled in the pressure bulkhead having an ignition control end and an ignition distribution end;
wherein the pressure igniter is sealed to at least a first threshold pressure;
wherein the pressure bulkhead and pressure igniter form a seal on the first end of the mandrel and thereby define a fixed volume for combustion gases; and
