No, it is 16" WITH the flashhider. The hider is pinned to the barrel. It IS possible to drill out the pin and remove the hider, but many people who try it give up and just use a hacksaw to cut the hider off. You cannou remove the barrel without taking the hider off - and the guys who want to SBR generall just give up and cut it off.
I do not know the thread size, but you could go to the Fn Forum and ask. I've seen it mentioned before.
However, once the hider comes off, you have a sub 16" barrel. Be aware of that.
