Upgrading to an Optac barrel and just wanted to check if the brass fitting is glued in our just pressed in?
Press it all the way in, and be sure not to push it out when you glue in the barrel.
How would one go about changing the barrel length on these once it’s glued in?
Apply heat and hope for the best?
If it’s super glue I use boiling water in a mug… let it heat then pull!
sometimes takes a few goes to do it.
I tend to not recycle t pieces… all of my barrels are epoxied into the t pieces anyway.
Being such a CYMA whore-boy and having a few of them I tend to buy new t-pieces in bulk… then when I swap out inner barrels I throw the old one in the parts tub. 
They all end up being used in another CYMA eventually. 
You don’t recycle
