the first contact surface defines the first configuration and the second contact surface defines the second configuration.

5. The adapter of claim 1 , wherein:

the second post portion abuts the first post portion at an angle relative to the longitudinal axis of the first post portion, the angle between 15 degrees and 45 degrees; and

a fastener couples the first and second post portions, wherein adjustment of the fastener causes the first and second post portions to slide relative to each other.

6. The adapter of claim 1 , further comprising:

a through passage in the first post portion, the through passage shaped to allow a fastener to pass therethrough and to allow the fastener to translate transversely relative to the longitudinal axis; and

a fastener engagement in the second post portion, the fastener engagement shaped to allow the second post portion to translate longitudinally relative to the fastener.

7. The adapter of claim 1 , wherein:

the second post portion is shaped to pass into a minimum diameter of a QD socket when the adapter is in the second configuration.

8. The adapter of claim 1 , wherein

the first and second tabs are shaped to engage one of a continuous annular groove in the QD socket, a discontinuous annular groove in the QD socket, or a plurality of openings in the QD socket.

9. A method of modifying a quick disconnect interface into a semi-permanent attachment point, comprising:

providing an adapter assembly having a plurality of tabs, the plurality of tabs movable between a first configuration having a first transverse distance between the plurality of tabs and a second configuration having a second transverse distance between the plurality of tabs, the first transverse distance greater than the second transverse distance;

loosening the adapter assembly to allow the adapter assembly to move from the first configuration to the second configuration;

inserting a distal portion of the adapter into a quick disconnect (QD) socket;

orienting an accessory attachment interface on the adapter assembly to a desired position; and

tightening the adapter assembly to cause the adapter assembly to move from the second configuration to an engagement configuration wherein the first and second tabs substantially oppose one another and engage an interior groove or a plurality of openings in the QD socket to selectively couple the adapter assembly to the QD socket.

10. The method of claim 9 , further comprising:

limiting rotation of a second post portion of the adapter assembly relative to a first post portion of the adapter assembly.

11. The method of claim 10 , further comprising:

limiting the second post portion to linear travel between the first configuration and the second configuration.

12. The method of claim 10 , further comprising:

causing a first contact surface in the first post portion to contact a first contact surface in the second post portion in the first configuration, the first contact surface in the second post portion perpendicular to a longitudinal axis of the second post portion; and

causing a second contact surface in the first post portion to contact a second contact surface in the second post portion in the second configuration, the second contact surface in the second post portion parallel to the longitudinal axis of the second post portion.

13. The method of claim 9 , further comprising:

adjusting a fastener to cause the adapter assembly to move between the first configuration and the second configuration.

14. The method of claim 9 , further comprising:

causing the plurality of tabs to engage one of a continuous annular groove in the QD socket, a discontinuous annular groove in the QD socket, or a plurality of openings in the QD socket.

15. The method of claim 9 , wherein:

the accessory attachment interface is a loop.

16. The method of claim 9 , wherein:

loosening comprises causing transverse movement of a first portion of the adapter assembly relative to a second portion of the adapter assembly, thereby narrowing an effective outer diameter of the distal portion of the adapter assembly; and

tightening comprises causing transverse movement of the first portion relative to the second portion, thereby widening an effective outer diameter of the distal portion of the adapter assembly.

17. An adapter for a quick disconnect (QD) socket, comprising:

a connection post having an attachment interface and a plurality of tabs movable relative to each other between a first configuration and a second configuration, the first configuration defining a maximum effective outer diameter of the connection post, and the second configuration defining a minimum effective outer diameter of the connection post; wherein

the plurality of tabs are at a first distance from a top of the connection post in the first configuration, and at least one of the plurality of tabs is offset from the first distance in the second configuration; and wherein

the plurality of tabs are shaped and positioned to engage an interior groove or a plurality of openings in the QD socket when in the first configuration.

18. The adapter of claim 17 , further comprising:

a guide mechanism shaped to limit rotation of the plurality of tabs relative to one another.

19. The adapter of claim 18 , wherein:

the guide mechanism comprises a travel stop shaped to limit the adapter to movement between the first configuration and the second configuration.

20. The adapter of claim 19 , wherein:

the travel stop comprises a first contact surface perpendicular to a longitudinal axis of the connection post and a second contact surface parallel to the longitudinal axis; and further wherein

the first contact surface defines the first configuration and the second contact surface defines the second configuration.

21. The adapter of claim 17 , wherein:

at least one of the plurality of tabs is translatable at an angle relative to another of the plurality of tabs at an angle, the angle between 15 degrees and 45 degrees.

22. The adapter of claim 17 , further comprising:

a fastener engagement in the connection post, the fastener engagement shaped to allow adjustment of the fastener to move the plurality of tabs between the first configuration and the second configuration.
