changing buffer tubes when switching barrels?

[tom burns]

Anyone know about this? Im switching out my carbine gas system for a mid length gas system

[TruEdge]

No need to change buffer tubes they work for both carbine and mid length. Only thing to worry about when switching barrels is to check headspacing.

They will both work fine with what you have now.

Both my rifles have carbine buffer tubes and buffer, although one is a middy and another a carbine, not needed I believe?

This right here. Leave the buffer tube alone and get some headspace gauges or have a gunsmith check headspace before firing your rifle if switching out barrels.
