A handguard attachment assembly for securing a handguard to a barrel assembly of a firearm. The assembly has a first body and a second body. Each of the first and second bodies includes a first side and a second side oppositely disposed. A first projection extends from the first side. A second projection extends from the second side. A first adjustable fastener is configured to couple the first projection of the first body and the second projection of the second body. A second adjustable fastener is configured to couple said second projection of said first body and said first projection of said second body.

A charging handle assembly for moving a bolt within a receiver of a firearm along a first axis includes a first body and a second body pivotable coupled to the first body. The first body has a projection configured to engage the bolt and a catch surface configured to engage a lock body of a latch coupled to the receiver. The second body has a projection extending from an outer surface towards the first axis. The second body is pivotable between a first position, wherein the protrusion is spaced from the latch and the catch surface can engage the lock body, and a second position, wherein the protrusion engages the latch to cause the lock body to disengage the catch surface of the first body to unlock the charging handle assembly from the latch.

An assembly for holding a bolt of a firearm in an open position is disclosed. The assembly comprises a bolt catch pivotable about a first axis toward and away from a catching position. In the catching position, a portion of the bolt catch is within a path of travel of the bolt. A follower transfer adapter is pivotable about a second axis. The follower transfer adapter includes an engagement portion that is configured to engage a follower of a magazine. Optionally, the follower transfer adapter includes an overhang lip that extends transversely to the longitudinal axis of the firearm and into a path of travel of the follower to define the engagement portion. The engagement portion is positioned between the second axis and the bolt catch along the longitudinal axis of the firearm. A linkage transfers rotational movement of the follower transfer adapter to rotation of the bolt catch.

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 located at a distal end of the fluid dissipation structure. The sleeve defines an internal volume that at least partially receives the fluid dissipation structure. The end cap assembly and the fluid dissipation structure at least partially define one or more distal chambers in communication with the internal volume. The end cap assembly defines an angled port.
