A gas plug retention and removal device (40) for a gas operating system (20) of a firearm (10). The gas operating system (20, 20') can include a gas block (30) comprising a front end (31a), a rear end (31b), a gas block bore (34) defined between the front and rear ends, and at least one cam engagement surface (58). A gas plug (26) can be removably received in the front end (3 Ia) of the gas block (30) for at least partially sealing the gas block bore (34), and a cam lever bail (42) can be pivotally coupled to the gas plug (26) and include at least one lever arm (52). The at least one lever arm (52) can be pivotally connected to the gas plug (26), be adapted to engage the gas block (30), and have at least one cam lobe (50) formed therealong. The at least one cam lobe (50) can engage the cam engagement surface (58) of the gas block (30) as the cam lever bail (42) is pivoted so as to disengage and facilitate the removal of the gas plug (26) from the gas block (30) to provide access to the gas block bore (34).
