FIELD OF THE DISCLOSURE

The disclosure generally relates to a firearm and more particularly relates to a suppressor assembly for a firearm.

BACKGROUND

Suppressor assemblies are configured to compensate for the various effects of firing a projectile (such as a bullet) from a firearm. Some of the effects include, but are not limited to, muzzle jump, muzzle recoil, muzzle blast, muzzle flash, and/or vibrations. For example, muzzle jump and muzzle recoil can adversely impact accuracy by altering the position of the firearm after each shot. Muzzle blast is the loud noise that generally accompanies the discharge of a firearm. Muzzle blast can damage the ears of the operator or nearby individuals not wearing ear protection and can bring unwanted attention in instances of covert use. Muzzle flash is the bright flash that generally accompanies the discharge of a firearm. Muzzle flash can adversely affect vision and draw unwanted attention to the use of the firearm. Excessive vibrations can impact the mechanical integrity of the firearm.

DETAILED DESCRIPTION

Overview

Described below are embodiments of a suppressor assembly (as well as individual components of the suppressor assembly) that can be attached to a firearm. Methods of installing and using the suppressor assembly on the firearm are also disclosed. The firearm may be a conventional firearm. For example, the firearm may be an M-16 style rifle, an AR-15 style rifle, an AR-10 style rifle, or an M-4 style rifle, among others. Any firearm may be used. The suppressor assembly may be configured to reduce the muzzle jump, muzzle recoil, muzzle blast, and/or muzzle flash generated by the firing of the firearm by slowing, expanding, trapping, and/or cooling the propellant gases associated with the firing of the firearm.
Generally speaking, the suppressor assembly may include an outer tube, a gas block, and a baffle. In certain embodiments, the outer tube may include an elongated hollow body having a first end and a second end. The first end may be configured to be attached to the gas block. For example, the first end may include internal threads that correspond to external threads on the gas block. In this manner, the first end of the outer tube may be screwed onto the gas block. The second end of the outer tube may include a front edge that is configured to abut a lip on the baffle.
The gas block may be positioned about a barrel of the firearm along a longitudinal length of the barrel. For example, the gas block may be attached to the barrel and spaced apart from a muzzle end of the barrel. In some instances, the gas block may include one or more gas ports in communication with a bore of the barrel. In addition, the gas block may be in fluid communication with a gas tube. In this manner, a portion of the propellant gasses may travel from the barrel, through the gas block, and into the gas tube. As noted above, the gas block may include external threads. The external threads on the gas block may be configured to mate with the internal threads on the first end of the outer tube. In this manner, the gas block may be configured to be attached to the first end of the outer tube. For example, the first end of the outer tube may be screwed onto the gas block.
In certain embodiments, the baffle may comprise a monocore baffle. That is, the baffle may be a single unibody assembly. The baffle may include a first end (e.g., an entry end) and a second end (e.g., an exit end). The second end of the baffle may include a lip. The lip may be configured to abut and compress against the front edge of the outer tube. The first end of the baffle may be attached to the muzzle end of the barrel. For example, the first end of the baffle may include internal threads that correspond to external threads on the muzzle end of the barrel. In this manner, the first end of the baffle may be screwed into the muzzle end of the barrel, thereby securing the baffle within the outer tube. The baffle may also include a bore configured to receive a projectile therethrough. The bore may extend between the first end of the baffle and the second end of the baffle. That is, the bore may extend through a longitudinal axis of the baffle.
As assembled, the first end of the outer tube can be attached to the gas block, and the first end of the baffle can be attached to the muzzle end of the barrel. The outer tube may form a chamber about at least a portion of the barrel of the firearm. In this manner, as the baffle is screwed (i.e., tightened) onto the muzzle end of the barrel, the lip at the second end of the baffle may engage and push against the front edge at the second end of the outer tube, which may place a compressive load on the outer tube. Similarly, as the baffle is screwed (i.e., tightened) onto the muzzle end of the barrel, the section of the barrel that extends past the gas block may be placed under tension, thereby reducing barrel vibrations caused by firing the firearm. The propellant gases associated with the firing of the firearm may be expanded, slowed, trapped, and/or cooled by the baffle and within the chamber. The propellant gases may then exit the suppressor assembly via the exit end of the baffle. As a result, the muzzle jump, muzzle recoil, muzzle blast, and/or muzzle flash generated by the firing of the firearm may be reduced or substantially eliminated.
These and other embodiments of the disclosure will be described in more detail through reference to the accompanying drawings in the detailed description of the disclosure that follows. This brief introduction, including section titles and corresponding summaries, is provided for the reader's convenience and is not intended to limit the scope of the claims or the proceeding sections. Furthermore, the techniques described above and below may be implemented in a number of ways and in a number of contexts. Several example implementations and contexts are provided with reference to the following figures, as described below in more detail. However, the following implementations and contexts are but a few of many.

The bore 112 may extend through the center of the barrel 110 along the longitudinal axis. The distal end of the barrel 110 may form the muzzle end 114 of the firearm 102. The muzzle end 114 may include external threads 115.
As depicted in FIG. 2-4, the suppressor assembly 100 may generally include an outer tube 116, a gas block 118, and a baffle 120. The outer tube 116, the gas block 118, and the baffle 120 may be configured to individually or collectively expand, slow, trap, and/or cool the propellant gases associated with the firing of the firearm 102. In some instances, the suppressor assembly 100 may be positioned about the barrel 110 and may be at least partially positioned within the hand guard assembly 106.
In certain embodiments, the gas block 118 may be positioned about the barrel 110. For example, the gas block 118 may be positioned about and attached to the barrel 110 at any location between the upper receiver 104 and the muzzle end 114 of the firearm 102. The gas block 118 may be attached to the barrel 110 by any means known in the art, such as, but not limited to, welded, screwed, bolted, pressure fitted, etc. In some instances, the gas block 118 may include one or more gas ports 122 in fluid communication with the bore 112 of the barrel 110. In addition, the gas block 118 may be in fluid communication with a gas tube 124 via the one or more gas ports 122. In this manner, a portion of the propellant gasses may travel from the barrel 110, through the gas block 118, and into the gas tube 124. The diverted portion of the propellant gases may be delivered to the upper receiver 104 via the gas tube 124. The gas block 118 may include external threads 126.
The outer tube 116 may include a first end 128 and a second end 130. The first end 128 of the outer tube 116 may be configured to be attached to the gas block 118. For example, the external threads 126 on the gas block 118 may be configured to mate with internal threads 132 on the first end 128 of the outer tube 116. In this manner, the gas block 118 may be configured to be attached to the first end 128 of the outer tube 116. For example, the first end 128 of the outer tube 116 may be screwed onto the gas block 118. Other attachment configurations between the outer tube 116 and the gas block 118 are also possible including, but not limited to, welding, pressure fitting, snapping-on, bolting, etc., the outer tube 116 to the gas block 118.
The second end 130 of the outer tube 116 may be configured to extend beyond the muzzle end 114 of the barrel 110 of the firearm 102. In this manner, the outer tube 116 may form a chamber 134 about at least a portion of the barrel 110 of the firearm 102. The chamber 134 may also extend at least partially beyond the muzzle end 114 of the firearm 102. The gas block 118 may form an end cap of the chamber 134. The other end of the chamber 134 may be closed off by the front face of the baffle 120. The second end 130 of the outer tube 116 may include a front edge 136 that is configured to abut and compress against a lip 138 at the front of the baffle 120. In some instances, the lip 138 may be omitted. In such instances, the baffle 120 may sit flush against the outer tube 116 or “float” within the outer tube 116.
The baffle 120 may comprise a monocore baffle. That is, the baffle 120 may be a single unibody assembly. The baffle 120 may include a first end 140 (e.g., an entry end) and a second end 142 (e.g., an exit end). The second end 142 of the baffle 120 may include the lip 138. The lip 138 may extend partially or fully about a circumference of the second end 142 of the baffle 120. The lip 138 may be configured to abut and push against the front edge 136 of the outer tube 116. As noted above, the lip 138 may be omitted. The first end 140 of the baffle 120 may be attached to the muzzle end 114 of the barrel 110. For example, the first end 140 of the baffle 120 may include internal threads 144 that correspond to the external threads 115 on the muzzle end 114 of the barrel 110. In this manner, the first end 140 of the baffle 120 may be screwed into the muzzle end 114 of the barrel 110, thereby securing the baffle 120 within the outer tube 116. Other attachment configurations between the baffle 120 and the muzzle end 114 of the barrel 110 are also possible including, but not limited to, welding, pressure fitting, snapping-on, bolting, etc., the baffle 120 to the muzzle end 114 of the barrel 110. The baffle 120 may also include a bore 146 configured to receive a projectile therethrough. The bore 146 may extend between the first end 140 of the baffle 120 and the second end 142 of the baffle 120. That is, the bore 146 may extend through a longitudinal axis of the baffle 120.
The first end 128 of the outer tube 116 can be attached to the gas block 118, and the first end 140 of the baffle 120 can be attached to the muzzle end 114 of the barrel 110. The outer tube 116 may form a chamber 134 about at least a portion of the barrel 110. In this manner, as the baffle 120 is screwed (i.e., tightened) onto the muzzle end 114 of the barrel 110, the lip 138 at the second end 142 of the baffle 120 may engage and push against the front edge 136 at the second end 130 of the outer tube 116, which may place a compressive load on the outer tube 116. Similarly, as the baffle 120 is screwed (i.e., tightened) onto the muzzle end 114 of the barrel 110, the section of the barrel 110 that extends past the gas block 118 may be placed under tension, thereby reducing barrel vibrations caused by firing the firearm 102. The propellant gases associated with the firing of the firearm 102 may be expanded, slowed, trapped, and/or cooled by the baffle 120 and within the chamber 134. The propellant gases may then exit the suppressor assembly 100 via the exit end (i.e., a second end 142) of the baffle 120. As a result, the muzzle jump, muzzle recoil, muzzle blast, and/or muzzle flash generated by the firing of the firearm 102 may be reduced or substantially eliminated.
The suppressor assembly 100 may be configured to reduce the muzzle jump, muzzle recoil, muzzle blast, muzzle flash, and/or vibrations generated by the firing of the firearm 102. That is, the suppressor assembly 100 may slow, expand, trap, and/or cool the propellant gases associated with the firing of the firearm 102. For example, a portion of the propellant gases may be initially diverted by the gas block 118 and delivered to the upper receiver 104 via one or more gas tubes or the like. The remainder of the propellant gases may exit the muzzle end 114 of the firearm 102 into the baffle 120 and the chamber 134. The propellant gases may then exit the suppressor assembly 100 by way of the exit end (i.e., the second end 142) of the baffle 120.

Illustrative Methods

FIG. 8 is a flow diagram depicting an illustrative method 200 for attaching the suppressor assembly 100 to the firearm 102 in accordance with one or more embodiments of the disclosure.
At block 202 of method 200, the gas block 118 may be attached to the barrel 110. That is, the gas block 118 may be positioned about the barrel 110 of the firearm 102 along the longitudinal length of the barrel 110. For example, the gas block 118 may be positioned about the barrel 110 at any location between the upper receiver 104 and the muzzle end 114 of the firearm 102.
Upon positioning the gas block 118 about the barrel 110 at block 202, the outer tube 116 may be attached to the gas block 118 at block 204. That is, the first end 128 of the outer tube 116 may be attached to the gas block 118. For example, the first end 128 of the outer tube 116 may include internal threads 132 that correspond to the 126 external threads on the gas block 118. In this manner, the first end 128 of the outer tube 116 may be screwed onto the gas block 118.
After the outer tube 116 has been attached to the gas block 118 at block 204, the baffle 120 may be positioned within the outer tube 116 and attached to the muzzle end 114 of the barrel 110 at block 206. For example, the first end 140 of the baffle 120 may include internal threads 144 that correspond to the external threads 115 on the muzzle end 114 of the barrel 110. In this manner, the first end 140 of the baffle 120 may be screwed into the muzzle end 114 of the barrel 110, thereby securing the baffle 120 within the outer tube 116. As the baffle 120 is screwed (i.e., tightened) onto the muzzle end 114 of the barrel 110, the lip 138 at the second end 142 of the baffle 120 may engage and push against the front edge 136 at the second end 130 of the outer tube 116, which may place a compressive load on the outer tube 116. Similarly, as the baffle 120 is screwed (i.e., tightened) onto the muzzle end 114 of the barrel 110, the section of the barrel 110 that extends past the gas block 118 may be placed under tension, thereby reducing barrel vibrations caused by firing the firearm 102.
