Abstract
A gas sealing device for a gas-operated firearm having a piston with a land surface positioned between a lateral flange and a peripheral rib, and a piston seal radially mounted on the land surface and positioned between the lateral flange and the peripheral rib. In operation, the piston and the piston seal can remain interlocked, but still operational so that upon firing, the piston is deflected towards the magazine tube due to the force applied by the piston seal. The piston seal exerts the force on the piston due to the impingement of a propellant gas charge on the piston seal.
