1. A quick-detach barrel mounting facility for a firearm having a receiver and a barrel comprising:
a barrel coupling portion at a rear end of the barrel;
a receiver coupling portion defining a central opening configured to receive the barrel coupling portion;
the receiver coupling portion defining a plurality of apertures;
the receiver coupling portion including a plurality of locking elements, each locking element received in one of the plurality of apertures and operable to reciprocate in the aperture between an engaged position protruding into the central opening and a disengaged position;
the receiver coupling portion including a latch element connected to the first body and having a locking surface proximate each of the apertures and configured to contact each of the locking elements;
the latch element being movable between an unlocked position in which the locking elements are enabled to move to the disengaged position and a locked position in which the locking elements are retained in the engaged position; and
the barrel coupling portion defining a depression configured for engagement by a locking element to secure the first body to the second body when the locking elements are in the engaged position, and to enable separation of the first body from the second body when the locking elements are in the disengaged position, such that the barrel is removable from the frame by moving the latch element to the unlocked position.
