Abstract
A combination receiver tube and adjustable stock for a firearm having a receiver. The receiver tube extends rearwardly from the receiver and includes a series of recessed locations formed along a length extending surface thereof, each of the recesses further including an ascending surface extending at an acute angle from the recessed location to an outer surface of the tube. The stock has a forward opening communicating with an open interior so that the stock is slidably mounted over the receiver tube to support axial movement of the stock relative to the tube. The stock includes a lug which is biased for seating within a first selected one of the recessed locations and, upon counter-biasing the lug to unseat from the recessed location, permitting the stock to be rearwardly extended from the receiver tube across consecutive recessed locations.
