ABSTRACT:
A sealing device for sealing the combustive gases of a caseless munition is mounted between a barrel and a firing chamber of a small caliber weapon. The sealing device includes a ring-shaped sealing element with a first end forming a radially extending sealing surface structured to press against the rear face of the barrel, and a second end includes an outwardly facing axially extending lip designed to press against an inner wall of the firing chamber. A cooling element reduces the rise in temperature of the sealing element, which comes into contact with the combustive gases.
