CLAIMS

What is claimed is:

Claim 1. A muzzle brake device for a firearm having a barrel with a muzzle extending along a longitudinal axis, the muzzle brake device comprising:

an elongated main body having a proximal end, a distal end, a first side section, a second side section that is positioned opposite to the first side section, and a central bore;

a first set of channels that are positioned within the main body, each of the first set of channels including a gas inlet section that is in communication with the central bore, and a gas discharge section that is in communication with the first side section; and

a second set of channels that are positioned within the main body, each of the second set of channels including a gas inlet section that is in communication with the central bore, and a gas discharge section that is in communication with the second side section,

wherein the first set of channels and the second set of channels include a mirror image arrangement to each other, relative to the central axis.

Claim 2. The device of claim 1, wherein each of the first set of channels and the second set of channels include a continuously curved shape along a single axis.

Claim 3. The device of claim 2, wherein each of the first set of channels and the second set of channels define an angle with a transverse axis to a longitudinal axis of the main body.

Claim 4. The device of claim 3, wherein the discharge section of each of the first set of channels and the second set of channels includes an angled portion extending upward from a bottom end of each channel.

Claim 5. The device of claim 1, wherein each of the first set of channels and the second set of channels include a shape, dimension and location that is configured to produce a valving effect for sequentially discharging a propellant gas from the muzzle brake.

Claim 6. The device of claim 5, wherein the discharge section of each of the first set of channels and the second set of channels is oriented at a generally opposite angle to a direction of a projectile traveling along the central bore.

Claim 7. The device of claim 1, wherein the inlet section of each of the first set of channels is oriented at an angle of between 270 and 360 degrees relative to the longitudinal axis of the main body.

Claim 8. The device of claim 7, wherein the discharge section of each of the first set of channels is oriented at an angle of between 180 and 270 degrees relative to the longitudinal axis of the main body.

Claim 9. The device of claim 1, wherein the inlet section of each of the second set of channels is oriented at an angle of between 0 and 90 degrees relative to the longitudinal axis of the main body.

Claim 10. The device of claim 9, wherein the discharge section of each of the second set of channels is oriented at an angle of between 90 and 180 degrees relative to the longitudinal axis of the main body.

Claim 11. The device of claim 1, wherein each of the first set of channels and the second set of channels include a shape, dimension and location that is configured to produce a valving effect for sequentially discharging between 90% and 100% of a propellant gas from the main body at a generally opposite angle to a direction of a projectile traveling along the central bore.

Claim 12. The device of claim 11, wherein the discharge section of each of the first set of channels and the second set of channels includes an angled portion extending upward from a bottom end of each channel,

said angled section being configured to direct the discharging propellant gas upward to reduce muzzle rise.

Claim 13. The device of claim 11, wherein the central bore comprises an internal diameter that is complementary to a diameter of the projectile.

Claim 14. The device of claim 13, wherein each of the first set of channels and the second set of channels are separated by a first distance.

Claim 15. The device of claim 14, wherein the first distance is complementary to a length of the projectile.
