1. A firearm stock comprising:
a body comprising:
an upper portion comprising an aperture configured to receive a receiver extension of a firearm,
a lower portion comprising a lower stock; and
a hollow cavity extending through the upper portion and a lower portion of the body and configured to house an outer spring, an inner spring, and a plunger;
the plunger slidingly arranged in the hollow cavity, and configured to couple to one or more buttons extending through at least one wall of the hollow cavity, and configured to engage with a locking means on the receiver extension of the firearm;
wherein
depressing the one or more buttons depresses the plunger to a first distance or a second distance, and
wherein depressing the plunger up to the first distance compresses the outer spring, allowing for adjustment of a length of pull by disengaging the plunger from the locking means on the receiver extension and reengaging the plunger with the locking means when the one or more buttons are released,
wherein depressing the plunger to a second distance, compresses both the outer spring and the inner spring, thereby allowing for detachment of the firearm stock from the fireman by disengaging the plunger completely from the receiver extension.
