Abstract
In an autoloading firearm, reloading is actuated by firing gases which are tapped from near the muzzle end of the barrel into a tubular magazine secured below the barrel. A reciprocating piston located inside the magazine is connected to a reloading mechanism and is driven to actuate the mechanism by the tapped gases. A cylindrical obturator is oppositely driven by the gases to scrape the interior of the magazine and serves as a valve to vent the gases.
