I came across a petition to the obama administration to remove supressors from the nfa. I doubt it will go anywhere, but it seems better than being quiet about it.
Here is the link if you are interested.

All the firearms laws of the 20th century need to be rewritten to reflect the modern era. Replace them all with a new, constitutional bill.
The constitution is fine as is, at least the first 10 amendments. Removal of legislation is what is needed, new legislation almost never increases freedom.
I posted this in the NFA forum. There’s been a discussion about it rolling for a week or two.
