Huben k1 .22 reg oring replacement

[oneshot61]

Does anyone have a link to a video that shows how to replace the oring under the regulator on a huben k2?? Or a tear down video?

Just checking if anyone has any additional videos. From start to finish? All the ones I've come across, the gun is already in pieces.
