Abstract
In one example, a firearm attachment includes a base adapted to be coupled to a firearm. The firearm attachment also includes a plurality of substantially longitudinal tines extending forwardly from the base and arranged circumferentially around a central axis of the attachment. The firearm attachment also includes at least one bore substantially concentric with the central axis. The firearm attachment also includes three longitudinal slots defined by sidewalls of adjacent ones of the tines and adapted to pass combustion gases from the bore. The sidewalls extend from the bore to an outer circumfery of the attachment. Sidewalls of adjacent tines lie in respective planes that intersect at an angle in a range of approximately 9 degrees to approximately 12 degrees. Other implementations and related methods are also provided.
Claims22
A firearm attachment comprising:
- a base adapted to be coupled to a firearm;
- a plurality of substantially longitudinal tines extending forwardly from the base and arranged circumferentially around a central axis of the firearm attachment, wherein the tines and at least a front portion of the base are adapted to be inserted into a socket of a firearm sound suppressor;
- a frusto-conical external surface substantially at a rear portion of the base and providing a plug configured to be received by a complementary interior surface of the socket;
- a tab extending longitudinally along the base from the plug and adapted to be received by a slot extending longitudinally along the firearm sound suppressor and disposed in the interior surface to rotationally align the firearm sound suppressor relative to the firearm, wherein the slot tapers from a maximum depth at a rear aperture of the socket to a minimum depth within the socket;
- at least one bore substantially concentric with the central axis;
- three longitudinal slots defined by sidewalls of adjacent ones of the tines and adapted to pass combustion gases from the bore;
- wherein the sidewalls extend from the bore to an outer circumfery of the firearm attachment;
- and
- wherein sidewalls of adjacent tines lie in respective planes that intersect at an angle in a range of approximately 9 degrees to approximately 12 degrees.
A method of aligning a firearm sound suppressor, the method comprising:
- coupling a base of a firearm attachment to a firearm;
- inserting a plurality of substantially longitudinal tines of the firearm attachment and at least a front portion of the base into a socket of the firearm sound suppressor, wherein the tines extend forwardly from the base and are arranged circumferentially around a central axis of the firearm attachment;
- sliding a tab of the firearm attachment into a slot disposed in an interior surface of the socket to rotationally align the firearm sound suppressor relative to the firearm;
- contacting a plug of the firearm attachment against the interior surface in a complementary engagement, wherein the plug is provided by a frusto-conical external surface of a rear portion of the base, wherein the tab extends longitudinally along the base from the plug, wherein the slot extends longitudinally along the firearm sound suppressor and tapers from a maximum depth at a rear aperture of the socket to a minimum depth within the socket;
- and
- wherein the firearm attachment further comprises:
- at least one bore substantially concentric with the central axis,
- three longitudinal slots defined by sidewalls of adjacent ones of the tines and adapted to pass combustion gases from the bore,
- wherein the sidewalls extend from the bore to an outer circumfery of the firearm attachment, and
- wherein sidewalls of adjacent tines lie in respective planes that intersect at an angle in a range of approximately 9 degrees to approximately 12 degrees.
