They actually make a 16.5", which it's really a moot point as I'll be cutting the barrel to sub-16" and having a brake permanently attached.

Maybe I'm going at this wrong, so feel free to comment. I'm looking for something in the 14.5" to 16" range that is going to have superb accuracy, but not too heavy. I say 14.5" to 16" because I can go 14.5" and run TBAC's flash hider, or I can go sub-16" and run their brake. I have one of their Ultra cans I plan on using.
