Isn't the TKO a larger diameter than the shroud? I have a 7" tube extension from Jim, and there isn't much of a gap between the shroud and airtube as it is, that it might interfere with the TKO.
Also, if you're adding that much length to the airtube and it's carbined, Jim makes a shroud extension so you drop in a M-rod barrel, which would get you to ~700fps without messing with the TP. Just an option, since those barrels are inexpensive.
