The tubing hanger retention system can also include multiple retention pin receiving features configured to be disposed, at least in part, within multiple tubing spool channels of a tubing spool. The tubing hanger retention system can further include multiple retention pins configured to be received by the retention pin receiving features, where each retention pin includes an engagement feature configured to be received by a retention pin receiving feature to place the retention pin in a captured state, where the engagement feature of each retention pin is further configured to enter into an engaged state with a retention ring channel when the retention pin is moved inward.
