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
An apparatus comprising:
- a barrel having an exterior, at least a region of which is non-round:
- a body mountable on the barrel;
- wherein at least some of the non-round region of the exterior is recessed and observable from a location forward of a muzzle end of the barrel, on an axis that is coaxial with a bore axis of the barrel, when the body is not mounted on the barrel;
- at least some of the non-round region of the exterior defines an alignment feature to restrict rotational movement of one of the body and the barrel relative to the other of the body and the barrel.
An apparatus, comprising:
- a barrel, wherein an exterior surface of the barrel comprises a non-threaded exterior having at least one discontinuity, the at least one discontinuity defining two or more surfaces;
- one or more gas ports to redirect, or vent, gas output from the barrel;
- and
- at least one part to orient one or more gas ports with the barrel by engaging at least one surface of two or more surfaces, the orientation including 1) restriction of a rotational orientation of the one or more gas ports or 2) restriction of fore/aft positioning of the one or more gas ports relative to the barrel.
An apparatus to mount to a front part of a length of a barrel to provide recoil reduction, the apparatus comprising:
- at least two parts including a barrel-mountable part having front end and a back end, the back end having an opening, wherein the opening includes a section arranged to fit around the front part of the length of the barrel;
- wherein the barrel-mountable part includes:
- a gas port;
- and
- an attachment interface associated with another part of the at least two parts;
- a body of the barrel-mountable part including a rear section located rearwardly of a plane coinciding with a rearmost portion of the gas port, a front section located forwardly of a plane coinciding with a frontmost portion of the gas port, and a remaining section, wherein the planes are perpendicular to a bore axis of the barrel;
- the attachment interface is defined, at least in part, by the remaining section or the front section, and the other part is located, at least in part, in the remaining section to secure the barrel-mountable part to the barrel.
An apparatus, comprising:
- at least one body 1) comprising a barrel, or 2) to fit around the barrel, the barrel including a muzzle one or more egresses in a length of the barrel, the at least one body to receive gas expelled from the one or more egresses in the length of the barrel;
- the one or more egresses having a first and second bottom exterior edges on different sides of a bore axis of a bore of the barrel;
- the at least one body including first and second surfaces to redirect at least some of the gas expelled from the one or more egresses, the first and second surfaces positioned so that:
- a first vector extending from the bore axis to the first bottom exterior edge of the one or more egresses collides with the first surface;
- and
- a second vector extending from the bore axis to the second different bottom exterior edge of the one or more egresses collides with the second surface;
- and
- the first and second vectors along a plane that is perpendicular to the bore axis.
The apparatus of claim 28, wherein the front face of the rear of the opening of the at least one opening is parallel with a surface of a front of the opening of the at least one opening.
