Trouble brewing ...

.
... in the NFA arena:

The bill would also increase the transfer tax on all weapons (except antique guns) covered under the National Firearms Act (which excludes most common guns) from $200 to $500 and index to inflation and  increase the transfer tax for any other weapon from $5 to $100.

I know that a lot of folks don't even know about the NFA mostly because suppressors and machine guns aren't in 'common use' these days (though suppressors are making inroads), and so there will probably be some support in general for this provision. It's therefore our responsibility to contact our legislators to make sure that this bill never gets off the ground.
