1. A silencer apparatus for suppressing a sound of a projectile fired from a firearm, the silencer apparatus comprising:
a first chamber and a second chamber, each of the first chamber and the second chamber having a cylindrical, oval, or rectangular shape;
the first and second chambers being aligned longitudinally and sequentially along a bore line, wherein the bore line is coaxial with a longitudinal bore axis of a barrel of the firearm when the silencer apparatus is installed on the firearm;
the first chamber comprising a first end cap on a proximal end thereof, and
the first end cap on a proximal side having a mechanical connection system for attaching the silencer apparatus to a muzzle end of the barrel of the firearm such that the bore line and longitudinal bore axis are aligned;
a second end cap concentric with the bore line and including a concentric annular opening around the barrel of the firearm and encompassing the barrel of the firearm, the second end cap having a mechanical connection system for attaching the silencer apparatus to the muzzle end of a barrel of the firearm such that the bore line and longitudinal bore axis are aligned;
a guide ring formed on a distal end of the second end cap, the guide ring being concentric with the bore line and the concentric annular opening of the first end cap, and
the guide ring being beveled along a distal side thereof and extending distally from the first end cap, the guide ring further securing the first chamber to the barrel along the bore line, the guide ring providing an interface and alignment guide for the second chamber coming into contact with the guide ring along the bore line;
the first chamber further including a first flange on a distal end of the first chamber and a mechanical spring;
the second chamber having a smaller diameter or cross-sectional area than the first chamber, the second chamber being wholly or partially inserted within the first chamber;
the second chamber having a radially outwardly facing second flange on a proximal end thereof, the proximal end of the second chamber being disposed inside the first chamber;
the mechanical spring being internal to the first chamber and biasing the second chamber into a retracted position in which the second chamber is retracted into the first chamber,
wherein the second chamber is movable relative to the first chamber longitudinally along the bore line from the retracted position to an expanded position, against the bias of the mechanical spring, when the second chamber is acted upon by expanding gases within the silencer apparatus,
wherein a proximal end of an inner tube within the second chamber contacts with the guide ring, such that a beveled portion of the guide ring causes the second flange and the second chamber to align concentrically with the bore line, when the second chamber is in the retracted position,
wherein the silencer apparatus allows a projectile fired from the firearm to travel along the bore line through the first chamber and the second chamber, when the silencer apparatus is installed on the muzzle end of the barrel of the firearm, and
wherein the first chamber, the second chamber, and the guide ring are concentric to the bore line, are positioned along a path of the projectile of the silencer, allow for a free flow path of the projectile, and are sized with one of a same diameter as the barrel or a diameter larger than the projectile.
