I haven't looked - I'm really not into the whole suppressor scene, as I don't hang onto any given firearm long enough to want to deal with the NFA paperwork cr@p. Now if they actually remove suppressors from the NFA list, I'd get a lot more interested.
It looks like it's been reintroduced and referred to committee.
