It should be appreciated that in actual use, an embodiment of the invention may be rotated as needed to accomplish the objectives of the invention. As a result of such rotation, the various terms used herein of “left,” “right,” “upper,” and “lower” and the like may not literally apply to a particular arrangement. Such terms are relative and are used herein to describe the Figures for illustration purposes only and are not intended to limit the embodiments shown to any particular orientation.

[0024] Referring now to FIGS. 1A-9, exemplary embodiments of a muzzle device and methods of use in accordance with the present disclosure are illustrated.

[0025] Turning to the Figures for illustrative purpose, FIG. 1A is a side elevation view of a muzzle device according to the present disclosure. The muzzle device 20 depicted in FIGS. 1A-1B generally includes a body 21, the body having a proximal end 22 and a distal end 23; a cylindrical wall 25 defining the body; a projectile opening 24 extending through the body; an attachment opening 26 on the proximal end of the device configured to attach to a muzzle end of a firearm; and a plurality of radial baffles and vent openings formed through the body of the device.

[0026] As illustrated in FIGS. 1A-1B, the muzzle device may include a first left baffle 27a, a first right baffle 27b, a second left baffle 28a, and second right baffle 28b, a third left baffle 29a, a third right baffle 29b, a fourth left baffle 30a and a fourth right baffle 30b. Additionally, the muzzle device shown in FIGS. 1A-1B includes a first left vent opening 32a defined by a lower wall 36a and an upper baffle wall 37a, a first right vent opening 32b defined by a lower wall 36b and an upper baffle wall 37b, a second left vent opening 33a defined by a lower baffle wall 38a and an upper baffle wall 39a, a second right vent opening 33b defined by a lower baffle wall 38b and an upper baffle wall 39b, a third left vent opening 34a defined by a lower baffle wall 40a and an upper baffle wall 41a, a third right vent opening 34b defined by a lower baffle wall 40b and an upper baffle wall 41b, a fourth left vent opening 35a defined by a lower baffle wall 42a and an upper baffle wall 43a, and a fourth right vent opening 35b defined by a lower baffle wall 42b and an upper baffle wall 43b. As shown in FIGS. 1A-1B, the muzzle device may further include one or more gas traps 31a, 31b, 31c and 31d formed in one or more of the upper baffle walls of the vent openings. Such gas traps are arranged and configured to trap additional gases exiting the firearm after firing. While the attached Figures, illustrate a muzzle device including four left baffles and four right baffles, and four left vent openings and four right vent openings, other embodiments are contemplated wherein more or less than four left baffles, four right baffles, four left vent openings, and/or four right vent openings are utilized, as will be appreciated by those skilled in the art. Furthermore, the device may be designed to include at least three rows of baffles rather than only two rows of left and right baffles as shown in the attached drawings.

[0027] Turning to FIG. 4, a muzzle device is illustrated showing a projectile 44 exiting through the projectile opening 24, which extends through the body of the muzzle device. The projectile opening of the muzzle device shown in FIG. 4 defines a bore hole extending longitudinally through the center of the body from the proximal end to the distal end.

[0028] As can be seen in FIG. 4, the lower wall 36a of the first left vent opening 32a and the lower wall 36b of the first right vent opening 32b converge. The projectile opening extends through both the lower wall 36a of the first left vent opening 32a and the lower wall 36b of the first right vent opening 32b. Likewise, the walls of the second left baffle 28a and the walls of the second right baffle 28b converge such that the upper baffle wall 39a of the second left vent opening 33a converges with the upper baffle wall 39b of the second right vent opening 33b, and the lower baffle wall 40a of the third left vent opening 34a converges with the lower baffle wall 40b of the third right vent opening 34b. Again the projectile opening 24 extends through the second left baffle and the second right baffle and through the upper walls of the second vent openings and the lower walls of the third vent openings. In the embodiment shown in FIGS. 1A-1B, the upper baffle wall 39a of the second left vent opening 33a is defined as two inclined walls which meet at an apex. Additionally the upper baffle wall 39b of the second right vent opening 33b is defined as two inclined walls which meet at an apex. The upper baffle wall 39a of the second left vent opening 33a converges with the upper baffle wall 39b of the second right vent opening 33b at the base of each respective wall, as can be seen in FIGS. 1A-1B. Other embodiments are contemplated wherein the upper baffle walls 39a and 39b of the second vent openings 33a and 33b and/or the fourth vent openings 35a and 35b are formed with a more rounded apex, as shown in FIGS. 3A and 3C. In such an embodiment, the upper baffle wall 39a of the second left vent opening 33a still converges with the upper baffle wall 39b of the second right vent opening 33b at the base of each respective wall, as can be seen in FIGS. 3A and 3C. Furthermore, the fourth left baffle 30a and the fourth right baffle 30b converge such that the upper baffle wall 43a of the fourth left vent opening 35a converges with the upper baffle wall 43b of the fourth right vent opening 35b. Again the projectile opening extends through the fourth left baffle and the fourth right baffle and through the upper walls of the fourth vent openings.

[0029] In contrast to the second and fourth baffles, wherein the left second baffle converges with the right second baffle and the second baffles extend all the way in to the center of the device and surround the projectile opening and wherein the left fourth baffle converges with the right fourth baffle and the fourth baffles extend all the way in to the center of the device and surround the projectile opening, the first left baffle 27a does not converge with or intersect the first right baffle 27b, such that the upper baffle wall 37a of the first left vent opening 32a does not converge with the upper baffle wall 37b of the first right vent opening 32b, and the lower baffle wall 38a of the second left vent opening 33a does not converge with the lower baffle wall 38b of the second right vent opening 33b. Additionally, the first left baffle 27a and the first right baffle 27b do not extend all the way in to the projectile opening 24, as can be best seen in FIG. 4. Void space is left between the edge of the first left baffle 27a and the projectile opening 24, and void space is left between the edge of the first right baffle 27b and the projectile opening 24. Likewise, the third left baffle 29a does not converge with or intersect the third right baffle 29b, such that the upper baffle wall 41a of the third left vent opening 34a does not converge with the upper baffle wall 41b of the third right vent opening 34b, and the lower baffle wall 42a of the fourth left vent opening 35a does not converge with the lower baffle wall 42b of the fourth right vent opening 35b. Additionally, the third left baffle 29a and the third right baffle 29b do not extend all the way in to the projectile opening. Void space is left between the edge of the third left baffle 29a and the projectile opening 24, and void space is left between the edge of the third right baffle 29b and the projectile opening 24, as can be best seen in FIG. 4. The void spaces between the interior walls of the first and third baffles and the projectile opening allow for more gas to exit through the radial vent openings rather than exiting through the projectile opening.

[0030] In one preferred embodiment contemplated herein, each of the baffles is positioned at an acute angle with respect to a longitudinal axis 45 of the muzzle device, as can be seen in FIG. 2. While the baffles may be positioned at a 45° angle to the longitudinal axis of the muzzle device, and in some cases, the baffles may be positioned at an angle greater than 45°, ideally the baffles will be positioned at an acute angle to the longitudinal axis of the device, such as an angle between 20° and 40°. Such angles are ideal in order to redirect and control the burst of combustion gases that follow the departure of a projectile from a firearm.

[0031] While the attached Figures illustrated the disclosed device with an attachment opening 26 configured to attach to the muzzle end of a firearm, please note that the disclosed device can be attached to a firearm using any attachment means known to those skilled in the art for attaching a muzzle brake or similar device to the muzzle end of a firearm. The proximal end of the disclosed device may be internally threaded or externally threaded to allow for attachment of the device to the muzzle end of a firearm. The disclosed device can be configured to be self-timing and easily indexed by the user. The disclosed device may also be configured for installation using a jam nut, crush washer or the like when attaching the device to the muzzle end of a firearm. Those skilled in the art will understand that many attachment methods are available, all of which are considered to be within the spirit and scope of the present disclosure.

[0032] In another preferred embodiment contemplated herein, FIG. 7 illustrates the disclosed device further including one or more ports 47 defined as holes or slots machined into the body of the device for counteracting muzzle rise. FIG. 6 illustrates an adjustable needle 46 which may be inserted into a slot arranged and configured to house the needle in the device. The adjustable needle 46 can be adjusted to either close off one or more of the ports 47 or to allow one or more of the ports to remain open. In order to counteract muzzle rise, the ports 47 should be positioned on the top face of the device when the device is attached to the muzzle end of a firearm.

[0033] Turning to FIGS. 8 and 9, the disclosed device may further include gas dispersion bars 51 extending through apertures 48 formed through the baffle walls. Such gas dispersion bars 51 may be useful for gas dispersion control, diverting sound and reducing muzzle flash. The gas dispersion bars 51 may extend through one or all of the vent openings formed through the body of the device 20. Additionally, the disclosed device may further include an attachment opening 49 for receiving and retaining a top cap 50 attached to the distal end of the disclosed device 20.
