Abstract

A modular noise suppressor for a firearm may have rearward and forward sections, and a front end cap. The rearward section may contain one or more baffles and can be configured to connect to the barrel of the firearm. The forward section can contain one or more baffles and may be connected to the rearward section. The front end cap can be connected to the forward section and provide a force to the baffles of the forward section. The connection between the rearward and forward sections can be in axial tension at least in response to the front end cap providing the force to the baffles of the forward section such that any loosening of the connection between the rearward and forward sections can be at least partially restricted in response to the axial tension.

First claim

The invention claimed is:

1. A modular noise suppressor for a firearm, comprising:
a first section including a mount configured for connection to the firearm, a body attached to the mount and defining an interior passage extending therealong, and at least one baffle received within the interior passage of the body;
a second section including an elongate body defining an interior passage with at least one additional baffle positioned therewithin, the second section configured to be removably connected to the first section such that the interior passages of the first section and second section are substantially aligned with one another, wherein other elongate bodies of different lengths can be substituted for the elongated body to enable reconfiguration of the noise suppressor to form extended and compact configurations of the noise suppressor; and
an end cap mountable to a front end of the second section and configured to apply an axial compressive force directed against the at least one additional baffle of the second section as the end cap is mounted to the front end thereof, wherein the axial compressive force is communicated through the at least one additional baffle of the second section to the first section so as to prevent relative movement between the first and second sections.

2. The modular noise suppressor according to claim 1 , wherein the axial compressive force directed against the at least one additional baffle of the second section generates an axial tension force between at least a portion of the body of the first section and at least a portion of the body of the second section sufficient to substantially restrict disengagement of the connection between the first section and the second section.

3. The modular noise suppressor of claim 1 , wherein the connection between the first section and the second section comprises a threaded connection.

4. The modular noise suppressor of claim 1 , further comprising at least one intermediate section connected to the first and/or second section, the at least one intermediate section including at least one baffle.

5. The modular noise suppressor of claim 1 , wherein the second section comprises a front tube, the first section comprises a rear tube, and the front tube has a rear end configured to be at least partially received within an interior passage of the rear tube.

6. The modular noise suppressor of claim 5 , wherein the rear tube at least partially encapsulates a series of baffles, and the front tube provides a rearwardly directed compressive force on a foremost baffle of the series of baffles so as to serially pass the compressive force on the foremost baffle through others of the series of baffles and apply a tensile force to the rear tube.

7. The modular noise suppressor of claim 6 , wherein each of the series of baffles comprises a baffle body including a base, a cone extending from the base, a passage allowing a projectile to pass therethrough, and at least one exhaust port defined therein, and wherein the series of baffles are arranged such that cones of the series of baffle are in an abutting relationship with bases of adjacent baffles.

8. The modular noise suppressor of claim 1 , wherein the mount of the first section comprises a recoil booster configured to at least partially reduce, absorb and/or redirect a recoil force of the firearm.

9. A method of forming a noise suppressor for a firearm, comprising:
connecting a forward section to a rearward section with at least one baffle of the forward section engaging at least one baffle of the rearward section, and with interior passages of the baffles of each of the forward and rearward sections in alignment;
mounting a front end cap to a front end of the forward section, the front end cap comprising a base having a projectile passage therethrough, and a rearwardly projecting side wall dimensioned to be received with the forward section and in engagement with the at least one baffle of the forward section; and
as the front end cap is mounted to the front end of the forward section, applying a substantially rearwardly-directed axial compressive force against the at least one baffle of the forward section by engagement of the end cap therewith and against the at least one baffle of the rearward section by the at least one baffle of the forward section, wherein an axial tension is created between the at least one forward section and the rearward section in response to the axial compressive force so as to restrict loosening of the connection therebetween.

10. The method of 9 , further comprising loosening a connection between the front end cap and the forward section sufficient to at least partially relieve the rearwardly directed axial compressive force applied by the front end cap to at least one baffle of the forward section and reduce the axial tension in the connection between the rearward and forward sections of the noise suppressor;
disconnecting the rearward and forward sections;
connecting a new forward section to the rearward section to form a different length or configuration suppressor; and
resecuring the end cap to the new forward section.

11. The method of claim 9 , further comprising connecting multiple additional, intermediate sections in series, between the rearward section and the end cap to define a modular silencer of a user selected length.
