If I understand what you’re asking, the length would be the same as that of the gas tube,from the BCA to the gas port.

That could be. However the diagrams appear to show measuring from the chamber end of the barrel extension.

I just buy the whole upper or the upper kit for the barrel length I want. No worries that way.

Del - Thanks for your help.
