Another of many PTFE guides for the X1C and the AMS. This one is a release button for the AMS hub.
The AMS hub has smaller holes than the AMS buffer; so it requires different release buttons.
You can find other models I have released for the X1C/AMS here:

If you appreciate my models, please consider buying me a coffee!
