Abstract
A firearm suppressor is adapted to convert from an over-barrel configuration to a muzzle-forward configuration. The firearm suppressor includes a core assembly that has a removable expansion chamber that can be included in the over-barrel configuration and removed in the muzzle-forward configuration. The firearm suppressor can be converted from the over-barrel configuration to the muzzle-forward configuration by removing the core assembly from a first hollow sleeve, removing the expansion chamber and inserting the core assembly into a shorter second sleeve.
Claims19
A firearm suppressor comprising:
- a hollow sleeve including an outer surface extending between an entry end and an exit end of the hollow sleeve;
- a locator cap connected at the exit end of the hollow sleeve, the locator cap including a central hole and a first alignment feature;
- a cylindrical body defining a longitudinal passage and a plurality of vents, the plurality of vents in fluid communication with the longitudinal passage and oriented at an angle with respect to a central axis of the longitudinal passage, the cylindrical body including a first end configured to removably attach to a barrel of a firearm and a second end positioned opposite to the first end;
- a centering ring connected to the cylindrical body at the second end, the centering ring including a second alignment feature that is configured to engage the first alignment feature on the locator cap to align the cylindrical body in the sleeve such that the central longitudinal passage is aligned with the central hole of the locator cap;
- a plurality of baffles received over the body and spaced apart from one another by a plurality of spacers, the plurality of baffles positioned between the plurality of vents to define a plurality of chambers between the hollow sleeve and the cylindrical body;
- an expansion chamber removably connected to the first end of the cylindrical body opposite to the centering ring, the expansion chamber extending away from the first end of the cylindrical body such that when the cylindrical body is attached to the barrel of the firearm, the expansion chamber surrounds a portion of the barrel;
- and
- an end cap removably connected to the entry end of the sleeve, the end cap contacting the expansion chamber to retain the expansion chamber and the cylindrical body in the hollow sleeve;
- wherein the firearm suppressor is operable in an over-barrel configuration in which the expansion chamber is positioned around a portion of the barrel of the firearm when the cylindrical body is attached to the firearm;
- and the firearm suppressor is operable in a muzzle-forward configuration in which the expansion chamber is removed and the hollow sleeve is replaced with a second hollow sleeve such that the firearm suppressor does not surround a portion of the barrel of the firearm.

A kit for assembling a firearm suppressor that is operable in an over-barrel configuration and in a muzzle-forward configuration, the kit comprising:
- a first hollow sleeve having a first length and including an outer surface extending between an entry end and an exit end of the first sleeve;
- a second hollow sleeve having a second length that is less than the first length, the second hollow sleeve extending between an entry end and an exit end of the second sleeve;
- a cylindrical body defining a central longitudinal passage and a plurality of vents, the plurality of vents in fluid communication with the longitudinal passage and oriented at an angle with respect to a central axis of the central longitudinal passage, the cylindrical body including a first end configured to removably attach to a barrel of a firearm and a second end positioned opposite to the first end;
- a centering ring configured to connect to the cylindrical body at the second end, the centering ring further configured to align the cylindrical body in the sleeve such that the central longitudinal passage is centered in the first sleeve or in the second sleeve;
- a plurality of baffles configured to be installed over the body and spaced apart from one another by a plurality of spacers, the plurality of baffles positioned between the plurality of vents to define a plurality of chambers between the first sleeve or the second sleeve and the body;
- an expansion chamber configured to removably connect to the first end of the cylindrical body opposite to the centering ring, the expansion chamber extending away from the first end of the cylindrical body such that when the cylindrical body is attached to a barrel of a firearm, the expansion chamber surrounds a portion of the barrel when the firearm suppressor is assembled in the over-barrel configuration;
- and
- an end cap configured to removably connect to the entry end of the first sleeve or the entry end of the second sleeve, the end cap contacting the expansion chamber to retain the expansion chamber and the cylindrical body in the first sleeve when the firearm suppressor is assembled in the over-barrel configuration, the end cap contacting the cylindrical body to retain the cylindrical body in the second sleeve when the firearm suppressor is assembled in the muzzle-forward configuration.

A method for converting a firearm suppressor from an over-barrel configuration to a muzzle-forward configuration, the method comprising:
- removing an end cap from a first sleeve of the firearm suppressor, the end cap including a threaded portion configured to removably connect the end cap to an entry end of the first sleeve;
- removing a core assembly from the first sleeve, the core assembly comprising:
- a cylindrical body defining a central longitudinal passage and a plurality of vents, the plurality of vents in fluid communication with the longitudinal passage and oriented at an angle with respect to a central axis of the central longitudinal passage, the cylindrical body including a first end configured to removably attach to a barrel of a firearm and a second end positioned opposite to the first end;
- a centering ring connected to the cylindrical body at the second end, the centering ring including a core alignment feature that is configured to engage a sleeve alignment feature to align the cylindrical body in the first sleeve such that the central longitudinal passage is centered inside the first sleeve;
- a plurality of baffles received over the cylindrical body and spaced apart from one another by a plurality of spacers, the plurality of baffles positioned between the plurality of vents to define a plurality of chambers;
- and
- an expansion chamber removably connected to the first end of the cylindrical body opposite to the centering ring, the expansion chamber extending away from the first end of the cylindrical body such that when the cylindrical body is attached to the barrel of the firearm, the expansion chamber surrounds a portion of the barrel;
- removing the expansion chamber from the core assembly;
- inserting the core assembly without the expansion chamber into a second sleeve, the second sleeve having a length that is shorter than a length of the first sleeve;
- connecting the end cap to the second sleeve to retain the core assembly without the expansion chamber inside the second sleeve.
