3838AST are listed for use with MC-AP. Connector has MCI-A rating in UL directory. The EGS connectors are also MCI-A rated. Even states it on the box. So unless you have a cable size discrepancy (outside of specified range), both look ok.
Although Southwire tries to be helpful with the chart, Southwire is not the final word. When MC-AP first came out as MC-Smart, there were few connectors with a MCI-A listing. Installers and inspectors were confused as to the correct connector. Now it is the opposite. Everybody has a MC connector(s) that is listed for MCI-A.
I do not know of a separate/additional listing for use with HCF. Anyone point out something here (besides the application chart)? Even the MC-AP HCF tag says to use just a MCI-A connector.

Even UL and the manufacturer of the connector cannot get it straight. Check out the difference in the cable ranges on the EGS connectors. Probably doesn't affect the rotation of the planet, but just interesting trivia.
On the box it reads 0.385 - 0.510
In the UL directory it reads:
For aluminum metal-clad interlocking armor cable Type (MCI-A), Cat. No.
AMC-50, cable diameter in. min. 0.406, max. 0.512.
