Abstract

A buffer tube for a firearm can include a body defining an interior cavity for receiving a buffer spring, and a rail disposed on and/or formed from the outer surface of the body. The rail can include one or more pin holes configured to receive a pin of a stock to lock the stock in a position, and a trunk opening defined at an end of the rail forming a first rail sidewall and second rail sidewall configured to receive a trunk of an actuator. The first and/or second rail sidewalls can include a slot defined therethrough configured to receive a pin associated with the trunk of the actuator to linearly guide the actuator. The rail can include a slide bar channel defined through at least a portion of the rail and configured to allow a slide bar to slide therein relative to the one or more pin holes to urge a pin out of a respective pin hole and/or to block a pin from being received by the pin holes.
