Abstract
A gas removal apparatus for an automatic firing weapon controlled by gas pressure contains a gas removal channel structure extending from a gas removal location to a gas receiving location and exhibiting one or two gas deflection locations as well as a gas throughflow element, such as a gas nozzle or gas throttle. Both the gas deflection locations and the gas nozzle or gas throttle are in danger of being eroded by the throughflowing gas. Therefore, these elements are constructed such that the gas erosion is as small as possible. According to the invention, this is attained by guiding a gas removal channel section or portion of the gas removal channel structure through a shrunk-fitted ring which is shrunk fitted onto the weapon barrel to a gas rail, by inserting the gas nozzle or gas throttle in the shrunk-fitted ring between the shrunk-fitted ring and the gas rail and by positioning a gas deflection insert in the gas rail.
