This is my stupid way to swap the inner barrel, probably not the best way to do it FOLLOW IT ON YOUR OWN RISK.
remove front sight/gas block, delta ring
there is 2 pin you need to remove,a big one and a small one; Small pin locks the inner barrel and the big one lock the black round thing (whatever you want to call it). DON'T pull the inner barrel out when you removed the small pin, because the small ball bearing will drop inside
Be careful when removing the grey ring, because a small ball bearing is under it and you don't want to loose the ball bearing!
Always remember which side of the grey ring face forward!
Add some oil/lub on the inner sider in the black ring. And you should be able turn the ring using a screw driver through the shell eject.
A little FAQs (will be update from time to time):
Q: The small pin that locks the inner barrel is very hard to put back in, any tips?
A: Try to push the inner barrel towards the receivers and put the pin in at the same time, this may help.
Q: Is there a way to take the Hop-Up unit out the upper receiver?
A: Remove the bigger pin and the "black round thing". Open up the receivers and you can use the charging handle pull the whole unit out from the back.
