HD AC cable connectors Junk.

The large hospital/research center that I retired from prohibited these style of connectors even in office spaces. Was told their thinking was a connector with a lock nut made a better mechanical connection to boxes.

That is what I would call an uninformed decision.

A few different manufacturers make that style of connector, probably whatever patents AFC Cable Systems had ran out.
Eddie mentioned Home Depot carries Halex and there actually is a Halex part number for them;

FLEX MC SNAP-IN CONNECTOR - Halex

If buy set screw, you mean the older type with just a screw then they can't be used on aluminum. The one screw saddle type has a foot under the screw to press against the cable armor.

That's what I was getting at, type where the screw makes direct contact with flex to secure it. Pretty sure that type never been acceptable for use with aluminum flex.
