Combined serrations for a firearm slide

A firearm assembly includes an upper receiver housing a bolt carrier group that is translatable within the upper receiver, and a lower receiver including a first hinge portion defining a first hinge opening. A second hinge portion is pivotally connected to the first hinge portion, and a buffer assembly is attached to the second hinge portion. A carrier block is positioned within the first hinge portion and is configurable in a blocking configuration and an unblocking configuration. A lock is configurable in a latched position and an unlatched position, and the lock is in mechanical communication with the carrier block when the lock is in the latched position. The carrier block is positioned in the unblocking configuration when the lock is in the latched position, and the carrier block is positioned in the blocking configuration when the lock is in the second position.
