Abstract

A system for sealing an indexing primer magazine and breech assembly of a barrel-type firearm to contain exhaust gases with the flow passage transfers the increased pressure into a sealing force between the insert and indexing primer magazine. Additionally, component parts of the seal are located out of the direct path of the formed exhaust gases to increase system longevity and safety. A seal is located within a recess of either the insert or indexing primer magazine, that is separated from the flow passage for the hot combustion gases from the primer or propellant charge.
