Abstract
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.
Claims30
A barrel including 1) a muzzle and 2) one or more ports to provide recoil reduction, the barrel including a bore defining one or more rifling discontinuities arranged to prevent projectile striping, the barrel comprising:
- a first section containing all of the one or more rifling discontinuities;
- a second section rearward of the first section;
- wherein each port of the one or more ports comprises an egress in a length of the barrel, wherein each egress comprises an interior opening and an exterior opening, and wherein an entire portion of each of the one or more interior openings is located in the first section of the barrel.
An apparatus, comprising:
- at least one body comprising, or operable with, a barrel;
- a gas port section defined by at least one body, the gas port section to provide recoil reduction and including a passage extending from an exterior of the at least one body to a bore of the barrel;
- the gas port section including a rib or other length characterized in that the rib or length is not perpendicular to a bore axis of the bore, and defines at least two non-contiguous gas output areas to expel gas from the gas port section;
- the rib or other length characterized in that it includes part of an exterior of the at least one body, and an exterior of the rib or other length is spaced apart, from the bore axis, a greater distance than a part of an exterior of the barrel is spaced apart from the bore axis, wherein the barrel is operable with a slide and said part of the exterior of the barrel fits into a barrel opening defined by the slide.
An apparatus to provide recoil reduction using gas supplied by a bore of at least one body, wherein the at least one body includes, or is operable with, a front mechanical sight, the apparatus comprising:
- at least two gas ports on different sides of a vertical plane, the vertical plane coincident with a bore axis of the bore and a line of sight associated with the front mechanical sight;
- the at least two gas ports characterized in that no gas port of the at least two gas ports is located completely forward of any other gas port of the at least two gas ports, optimizing a proximity of an aggregate output area of the at least two gas ports to a frontmost end of the at least one body;
- the at least two gas ports further characterized in that central axes of the at least two gas ports, respectively, are not parallel, and at least a portion of the at least two gas ports is located forwardly of a rearmost part of the front mechanical sight.
The apparatus of claim 31, wherein the at least one body comprises a top side, wherein the at least two gas ports are defined, at least in part, by the top side of the at least one body.
The apparatus of claim 31, wherein each gas port of the at least two gas ports independently generates a net force having a non-zero downward component, the non-zero downward component opposite a direction associated with recoil.
The apparatus of claim 31, wherein the at least one body includes a rib or other length defining a pair of gas ports of the at least two gas ports.
A method of processing a rifled barrel for operation in a firearm employing an integrated compensation system having one or more gas ports, the method comprising:
- providing a rifled barrel having one or more openings to expel gas, wherein the one or more openings include at least a muzzle;
- and
- forming at least one rifling discontinuity in a bore of the barrel using a tool inserted into an opening of the one or more openings, wherein in a case that the opening comprises 1) the muzzle and 2) one or more egresses in the length of the barrel, the rifling discontinuity extends from the muzzle to a location coinciding with rearmost part(s) of the one or more egresses.
