US12510321 - Gas port geometry

A firearm or firearm retrofit assembly may include a compensation assembly to receive gas expelled from a muzzle of a barrel or an egress in a length of the barrel. The compensation assembly may include one or more gas flow-directing sections to tune the flow of gas through the compensation assembly, which may reduce recoil. Other embodiments may be disclosed and/or claimed.

firearmgasportrecoilreductioncompensator

The patent describes a compensator for firearms designed to reduce recoil by utilizing a gas port section that redirects gas expelled from the barrel through multiple openings. The unique geometry of the gas port and its ribbed structure optimizes gas flow and enhances the compensator’s effectiveness in managing recoil.

Claim 1

1 . An apparatus, comprising: a compensator having a body; a cavity in a gas port section of the body, the gas port section to provide recoil reduction and located rearwardly of an opening a projectile exits a firearm, the cavity to receive and redirect, or vent, a portion of gas traveling toward the opening; the cavity characterized in that the cavity expels the portion of the gas out plural openings, no opening of the plural openings located completely forward of any other opening of the plural openings, optimizing a proximity of an aggregate output area of the plural openings to a front end of the compensator, the gas port section including a rib or another length characterized in that the rib or the other length defines at least two non-contiguous areas of the aggregate output area; the rib or the other length further characterized in that the rib or the other length includes part of an exterior of the body, the part of the exterior of the body is spaced apart, from a bore axis, a greater distance than a radius of a barrel opening through which a barrel section of the firearm passes; wherein the part of the exterior of the body is not perpendicular to the bore axis of the barrel section. a compensator having a body; a cavity in a gas port section of the body, the gas port section to provide recoil reduction and located rearwardly of an opening a projectile exits a firearm, the cavity to receive and redirect, or vent, a portion of gas traveling toward the opening; the cavity characterized in that the cavity expels the portion of the gas out plural openings, no opening of the plural openings located completely forward of any other opening of the plural openings, optimizing a proximity of an aggregate output area of the plural openings to a front end of the compensator, the gas port section including a rib or another length characterized in that the rib or the other length defines at least two non-contiguous areas of the aggregate output area; the rib or the other length further characterized in that the rib or the other length includes part of an exterior of the body, the part of the exterior of the body is spaced apart, from a bore axis, a greater distance than a radius of a barrel opening through which a barrel section of the firearm passes; wherein the part of the exterior of the body is not perpendicular to the bore axis of the barrel section.
