Abstract:
1. A system for use with a rifle, said system comprising: a gas block, said gas block having a barrel bore and a gas plug bore, both extending completely through said gas block, said barrel bore and said gas plug bore being substantially parallel one to the other, said barrel bore being configured to receive a barrel securely inserted therein, said barrel bore having an aperture being configured to receive a discharge gas from a gas port formed through said barrel proximate to a muzzle of said rifle, said aperture extending from said barrel bore to said gas plug bore, said aperture directing said discharge gas towards said gas plug bore, said gas block being secured to said barrel substantially preventing movement of said gas block relative to said barrel and being configured to transport said discharge gas from said barrel to said gas plug bore, said gas plug bore having a muzzle end opening towards said muzzle and a breech end opening towards a breech of said rifle; a gas plug, said gas plug being secured within said gas plug bore by a securing means, an exhaust portion of the gas plug having a breechward orientation; said gas plug having a passage being formed internally, said discharge gas passing from said aperture to said passage and towards said exhaust portion; a bolt carrier key, said bolt carrier key being configured to move synchronously with a bolt carrier; a rod, said rod being configured as a single part or a securely connected assembly, a first end of said rod being coupled to said gas plug, a second end being coupled to said bolt carrier key; an actuating means, said actuating means forming an actuation coupling between said gas plug and said rod, said actuating means imparting a kinetic energy of the high pressure said discharge gas on said rod, said actuating means permitting said rod to be actuated linearly in a breechward direction; said actuating means comprising: a hollow rod, said hollow rod being formed by said exhaust portion of said gas plug; an exhaust outlet, said exhaust outlet being formed at a terminus of said exhaust portion, said exhaust outlet permitting the expelling of said discharge gas; a sleeve, said sleeve being formed by said first end of said rod, said first end being generally hollow forming said sleeve, said hollow rod being configured to nest within the hollow portion of said sleeve, a gap being formed therebetween; wherein, upon the firing of a round, said discharge gas under pressure is expelled from said exhaust outlet, said discharge gas imparting said force into said sleeve by impingement of said gas on said sleeve, said sleeve resultantly translating breechward thus causing a breechward motion of said rod; and wherein said discharge gas is released to the atmosphere through an exhaust port via said gap; a biasing means, said biasing means urging said rod towards said gas plug with an urging force, said biasing means permitting translational movement of said rod when said urging force is exceeded by said actuating means; wherein, upon the firing of a round, said discharge gas under pressure is diverted into said gas port of said barrel, said discharge gas then being transported to said aperture, said discharge gas thereafter being delivered into said passage of said gas plug; and wherein, said discharge gas provides a force to the actuating means, said actuating means causing said breechward motion of said rod translationally; and wherein, said rod thereafter actuates said bolt carrier key causing a breechward translation of said bolt carrier, said breechward translation activating said bolt carrier and an extractor; and wherein said rod can be uninstalled without removal of a hand guard or said gas block by extracting said gas plug from said gas plug bore from said muzzle end, said rod being extractable through said gas plug bore thereafter by a user in a single piece upon extraction of said gas plug.
