Abstract

A suppressor, an integrally suppressed barrel system, and a method for coupling a suppressor to a firearm barrel are provided. In an embodiment, a suppressor is configured to have two distinct fittings, each of which provides a point of contact for coupling with a firearm barrel. The suppressor or integrally suppressed barrel system may comprise an expansion chamber with an expansion chamber baffle and wire mesh to alter the sonic characteristics of a report associated with the discharging of a firearm. In some embodiments, the expansion chamber baffle may be movable, allowing for modification to the sonic properties of a cold bore shot vis-à-vis subsequent shots. The method for coupling the suppressor to the firearm barrel includes engaging first and second threaded portions of the firearm barrel with corresponding threaded inner surfaces of first and second suppressor fittings.

Dependent claims

An apparatus for reducing an audible report of a firearm, the apparatus being coupleable with a barrel of the firearm, the apparatus comprising:

a tubular housing having a first end and a second end opposite the first end, the first end configured for discharging a projectile fired by the firearm and the second end configured to receive the barrel of the firearm;
a first disk shaped body disposed within the tubular housing in a first position and having a first through hole defining a first inner surface and at least one aperture extending through the first disk shaped body from a first face of the first disk shaped body to a second face of the first disk shaped body, the first face of the first disk shaped body opposite the second face of the first disk shaped body, wherein at least a portion of the first inner surface is threaded and configured to mate with a first threaded portion of the firearm barrel;
and
a second disk shaped body having a first face and a second face opposite the first face, disposed within the tubular housing in a second position and having a second through hole defining a second inner surface, at least a portion of the second inner surface being threaded and configured to mate with a second threaded portion of the firearm barrel to sealingly engage with the second threaded portion of the firearm barrel at each of the first face and the second face of the second disk shaped body,
wherein the first position and the second position are spaced apart by a first longitudinal distance, the first longitudinal distance defining an expansion chamber within the tubular housing, and wherein the first position is nearer the first end than the second position;
a third disk shaped body disposed within the tubular housing in a third position and having a third through hole defining a third inner surface, the third position being between the first position and the second position;
and
a fourth disk shaped body disposed within the tubular housing at the first end of the tubular housing consisting of a single fourth through hole fitting defining a fourth inner surface.

5 more elements

An integrally suppressed firearm barrel system, the system comprising:

a suppressor, the suppressor comprising:
a housing having a first end and a second end opposite the first end, the first end configured for discharging a projectile fired by a firearm and the second end configured to receive the barrel of the firearm;
a first barrel receiving fitting disposed at a first position within the housing, the first barrel receiving fitting having a threaded through hole that defines a first inner surface and at least one aperture extending through the first disk shaped body from a first face of the first disk shaped body to a second face of the first disk shaped body, the first face of the first disk shaped body opposite the second face of the first disk shaped body;
and
a second barrel receiving fitting disposed at a second position within the housing, the second barrel receiving fitting having a threaded through hole that defines a second inner surface, wherein the second barrel receiving fitting is configured to sealingly engage with a second threaded portion of a firearm barrel at each of a first face and a second face of the second barrel receiving fitting;
a third disk shaped body disposed within the housing in a third position and having a third through hole defining a third inner surface, the third position being between the first position and the second position;
and
a fourth disk shaped body disposed within the housing at the first end of the housing consisting of a single fourth through hole fitting defining a fourth inner surface;
and
the firearm barrel, the firearm barrel comprising:
a first threaded portion, wherein the first threaded portion is on an outer-facing surface of the firearm barrel at a first position;
and
the second threaded portion at a second position, the first position being nearer the first end of the housing than the second position;
wherein a distance separates the first threaded portion from the second portion, and wherein at least a portion of the first barrel receiving fitting is configured to receive and mate with the first threaded portion of the firearm barrel and the second barrel receiving fitting is configured to receive and mate with the second threaded portion of the firearm barrel.

11 more elements

A method for coupling a suppressor to a barrel of a firearm, the method comprising:

inserting a first portion of the barrel of the firearm into a first portion of a suppressor housing, the suppressor housing comprising a first threaded suppressor component and a second threaded suppressor component;
engaging a first threaded portion of the barrel of the firearm with the first threaded suppressor component, the first threaded suppressor component disposed within the tubular housing in a first position and having a first through hole defining a first inner surface and at least one aperture extending through the first disk shaped body from a first face of the first disk shaped body to a second face of the first disk shaped body, the first face of the first disk shaped body opposite the second face of the first disk shaped body;
and
engaging a second threaded portion of the barrel of the firearm with the second threaded suppressor component, the second threaded suppressor component having a first face and a second face opposite the first face and disposed within the tubular housing in a second position, wherein the second threaded suppressor component comprises a second through hole defining a second inner surface, at least a portion of the second inner surface being threaded and configured to mate with a second threaded portion of the firearm barrel to sealingly engage with the second threaded portion of the barrel of the firearm at each of the first face and the second face of the second disk shaped body,
wherein the suppressor further comprises:
a third disk shaped body disposed within the suppressor housing in a third position and having a third through hole defining a third inner surface, the third position being between the first position and the second position, and
a fourth disk shaped body disposed within the suppressor housing at a discharging end of the suppressor housing, consisting of a single fourth through hole fitting defining a fourth inner surface.
