Abstract
A side-discharge muzzle brake includes a body, which includes an attachment portion and multiple ports located in the wall of the body. The side-discharge muzzle brake further includes a sleeve sized to slide over a portion of the body and to be rotatable around the body. The sleeve includes multiple openings. The side-discharge muzzle brake includes a securing assembly that allows that sleeve to be rotatable around the portion of the body in two directions for a full 360 degrees of rotation.
Claims18
A muzzle brake comprising:
- a body having a hole that extends through the body in a lengthwise direction, the body including:
- a mounting portion including internal threading in the hole on a first end of the mounting portion coinciding with a first end of the body,
- a plurality of notches located on a second end of the mounting portion that is opposite the first end of the mounting portion,
- a vent portion extending from the second end of the mounting portion, the vent portion including at least a pair of vent apertures disposed such that a first vent aperture is disposed through a wall of the vent portion into the hole in the body and a second vent aperture is disposed opposite the first vent aperture through the wall of the vent portion into the hole in the body, the pair of vent apertures oriented in the wall of the vent portion such that, when the muzzle brake is attached to a firearm, the pair of vent apertures are oriented on a horizontal plane to vent combustion gas substantially parallel to the horizontal plane,
- a threaded portion extending from the vent portion, the threaded portion including external threading on a surface of the body outside the hole, and
- a shoulder between the vent portion and the threaded portion;
- a sleeve sized to slide over the vent portion of the body, the sleeve including:
- a plurality of detents located at an end of the sleeve and sized to engage the plurality of notches, respectively, such that the plurality of detents maintains a position of the sleeve, and
- at least a pair of exit apertures disposed such that a first exit aperture is disposed through a wall of the sleeve and a second exit aperture is disposed opposite the first exit aperture through the wall of the sleeve, the pair of exit apertures oriented in the wall of the sleeve such that:
- when the sleeve is rotated into a first position, the pair of exit apertures are oriented to align with the pair of vent apertures, and
- when the sleeve is rotated into a second position, the pair of exit apertures are oriented to not align with the pair of vent apertures;
- and
- a nut that is removably attachable to the threaded portion of the body such that the nut maintains the sleeve on the body,
- wherein the sleeve is rotatable about the vent portion of the body in two directions for a full 360 degrees of rotation between the first position and the second position.

A side-discharge muzzle brake comprising:
- a body having a hole that extends through the body in a lengthwise direction, the body including:
- an attachment portion including internal threading in the hole on a first end of the attachment portion coinciding with a first end of the body and multiple notches located on a second end of the attachment portion that is opposite the first end of the attachment portion, and
- multiple ports located through a wall of the body, the multiple ports located in the wall of the body, such that, when the side-discharge muzzle brake is attached to a firearm, the multiple ports are oriented on a horizontal plane to vent combustion gas in a direction that is substantially parallel to the horizontal plane;
- a sleeve sized to slide over at least a portion of the body and to be rotatable around the body, the sleeve including multiple openings and multiple detents configured to be insertable into the multiple notches such that the multiple detents maintain a position of the sleeve unless a rotatable force is applied to the sleeve, the rotatable force exceeding a threshold force in order to rotate the sleeve concentrically around the body;
- and
- a securing assembly configured to secure the sleeve on the body of the side-discharge muzzle brake, such that the sleeve is rotatable about the portion of the body in two directions for a full 360 degrees of rotation.
3 more elements
An actuatable muzzle brake comprising:
- a body including:
- one or more vents configured to vent combustion gas, and
- one or more notches located on a lip of the body;
- and
- a rotatable sleeve configured to slide over at least a portion of the body, the sleeve including:
- one or more apertures configured to align with the one or more vents in a first position, the one or more apertures being sized such that a continuous portion of the sleeve completely covers the one or more vents in a second position, and
- one or more detents configured to engage with the one or more notches such that the one or more detents maintain a position of the sleeve unless a rotatable force is applied to the sleeve, the rotatable force exceeding a threshold force in order to rotate the sleeve concentrically around the body,
- wherein the one or more vents are oriented substantially parallel to a horizontal plane when the actuatable muzzle brake is installed on a firearm, such that the actuatable muzzle brake discharges combustion gas out sides of the actuatable muzzle brake.
