A combination back strap and grip extender mountable on a grip of a firearm. The grip defines a magazine well. The combination comprises a strap positionable lengthwise along and overlying an anterior portion of said grip. The strap has first and second ends oppositely disposed. The first and second ends are removably attachable to said grip. The grip extender is mounted on said second end of said strap. The grip extender comprises a collar defining a lumen aligned with said magazine well when said strap overlies said grip.

A bolt catch is movably mounted on a firearm. A first surface of the bolt catch is configured to engage a bolt to retain the bolt in a first position. The bolt catch has a second surface that is configured to engage a follower of a magazine when the magazine is empty to position the bolt catch in a catching configuration in which the first surface is within a path of travel of the bolt. The bolt catch includes an elongate slot that extends transversely through the bolt catch. A pin extends through the slot of the bolt catch. The bolt catch is configured to pivot about the pin and slide relative to the pin. A spring biases the bolt catch rearwardly. Upon engagement between the bolt and the first surface of the bolt catch, the bolt catch is configured to slide relative to the pin to compress the spring.

A charging slide for carrying a bolt and latching a firearm in a folded position. The charging slide comprises a body, a projection, and a grip. The projection extends away from a first surface of the body along a first axis. The projection is configured to engage the bolt. The grip extends away from a first side of the body along a second axis oriented transversely to the first axis. The grip comprises a surface configured to engage an edge of a slot in a handguard of the firearm when the firearm is in the folded position. A receiver assembly and foldable firearm comprising the charging slide are also included.

An arrangement of a hammer and a sear for a firearm having a frame is disclosed. The arrangement includes a hammer mountable within said frame for pivoting motion about a hammer pivot axis. The hammer includes a hammer body defining a hammer lug surrounding said hammer pivot axis and a hammer face positioned distal to said hammer pivot axis. A slot is positioned within said hammer body. A catch surface is positioned on said hammer body within said slot. A sear is mountable within said frame for pivoting motion about a sear pivot axis. The sear includes a sear body defining a sear lug surrounding said sear pivot axis and an action surface positioned on said sear body distal to said sear pivot axis. The action surface is movable into and out of engagement with said catch surface upon rotation of said sear body about said sear pivot axis. At least a portion of said sear body is received within said slot.

A firearm accessory and an end cap useful with the firearm assembly. The firearm assembly handles exhaust gas expelled with a round fired from a firearm and includes a fitting, a sleeve, a fluid pressure dissipation structure, and an end cap assembly at a distal end of the dissipation structure. The sleeve defines an internal volume that at least partially receives the dissipation structure. The end cap assembly and the dissipation structure at least partially define one or more distal chambers communicating with the internal volume. The end cap assembly defines a first, a second, and a third passage, each communicating with an exterior of the accessory. The first passage allows a bullet to pass through. The second passage includes a port in the end cap assembly radially outward of the first passage. The third passage includes a port located radially outward from the port of the second passage.

A suppressor baffle and a firearm suppressor for suppressing the volume of the report of a firearm includes a fitting for mounting the suppressor on a firearm, a sleeve, and a baffle assembly. The sleeve is supported by the fitting. The baffle assembly is at least partially received in an internal volume defined by the sleeve. A first baffle in the plurality of baffles has a conical section with a proximal opening and a port. The port is elongate in a direction along the circumference of the conical section. The port provides a fluid path through the conical section from an entrance chamber of the suppressor to an internal conical volume defined by the conical section. Gas flowing along the first baffle is directed through the port, causing energy dissipation in the gas.

A recoil buffer assembly for cushioning the impact of recoiling components of a firearm. The recoil buffer assembly comprises a first spring, a second spring, and a buffer. The first spring extends along a first axis. The second spring extends along the first axis. The buffer is positioned between a first end of the second spring and a second end of the first spring. The first spring is configured to act between the buffer and a bolt within the firearm. The second spring is configured to act between an end of the firearm and the buffer. A receiver assembly and firearm comprising the recoil buffer assembly are also included.
