Abstract: A stock has a buttstock. The buttstock includes an adjustable comb. The comb is connected to a body of the buttstock via a rod extending into the body of the buttstock and movable along a first axis. The position of the rod and comb is locked and unlocked by a latch. The buttstock includes an adjustable recoil pad. The recoil pad is connected to the body via a threaded rod mated with a nut embedded within an end of the body. The threaded rod and recoil pad move a direction along a longitudinal axis of the body depending on the rotation of the nut.

Abstract: 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.

Abstract: A latch for securing a buttstock to a receiver of a firearm. The buttstock has at least one compartment configured to receive a spare magazine. The latch comprises a shaft, a lever, a first spring, and a second spring. The shaft moves along a first axis within the buttstock and is biased by the first spring to engage with a recess in a receiver of the firearm. The lever extends along a second axis transverse to the first axis and is positioned between the buttstock and an end of the shaft. The second spring biases the lever toward the buttstock. The lever includes a projection configured to extend through an opening in the buttstock and engage with the spare magazine. The lever is pivotable and is configured to release the magazine when the lever is pivoted in a first direction.

Abstract: A trigger return and safety mechanism are mountable on a frame of a firearm. The trigger is mountable on the frame and pivotable about a trigger pivot axis. A strut is pivotably attached to the trigger at a strut pivot axis oriented parallel to and offset from the trigger pivot axis. The strut comprises a spring bearing surface and a safety bearing surface. A spring acts between the spring bearing surface and the frame for biasing the trigger into a reset position after the trigger has been pulled. A body is mountable on the frame, the body being movable between a first position wherein the body is not engageable with the safety bearing surface, thereby allowing pivoting motion of the trigger, and a second position wherein the body is engageable with the safety bearing surface thereby limiting pivoting motion of the trigger.

Abstract: A charging handle assembly for a rifle has a body extending along a first axis. The body comprises a first side, a second side oppositely disposed, and an opening therebetween. A first handle is connected to the first side and extends away from the body along the first axis. A second handle is connected to the second side and extends away from the body along the first axis. A rod, comprising a first end and a second end, extends through the opening along a longitudinal axis oriented transversely to the first axis. A return spring acts between the body and the first end of the rod and biases the body towards the second end of the rod. The body is movable between the first end and the second end of the rod and compresses the spring when moving towards the first end.

Abstract: An ammunition magazine is disclosed including a tube surrounding a central space and having first and second ends oppositely disposed and having a first opening being positioned at the first end providing access to the central space. A spacer surrounds the tube proximate to the first end. A catch plate is integrally formed with the spacer. A butt plate is attached to the first end and overlies a portion of the spacer. The spacer being is captured between the butt plate and the tube. A fastener is positioned on the catch plate and engages the butt plate to retain the butt plate to the spacer.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
