Does a working 802.11ac Wireless USB Adapter exist for OpenWrt?

I want to buy a 802.11ac dual band Wireless USB Adapter like the Alfa AWUS036ACS but i can't find information which one actually works with OpenWrt.

I want to use the adapter as a wireless client with

Raspberry Pi 3 Model B Plus Rev 1.3 and
OpenWrt SNAPSHOT r13911-b057862e24 / LuCI Master git-20.201.65700-7edd635

Now I use an old Alfa AWUS036H adapter as a wireless client.
I'm looking for an adapter with more capacity. In the current situation I get no more then 8 Mbps with my laptop connected to the Raspberry Lan port and 6 Mbps with my laptop wireless connected with the internal 5 GHz wireless radio of the Raspberry Pi as master.

Can anybody share experience or guide me to information which one I can buy?

There should be a couple of devices supported by mt76-usb (mt7610e), but you don't really want any USB device for 24/7 operations or AP mode.

I'm looking for an USB adapter as STA, not for AP mode perse.
I think of AWUS036ACM (Mediatek) or AWUS036NHA (Atheros).
Any advice?
