The stuff that I want changed at the federal level is removal of Hughes, suppressors, and short barrel long guns from the NFA. That all requires Congress and it's not going to happen outside of SCOTUS striking those laws down, which SCOTUS has been hesitant to touch in Federal firearms laws. They have no issues striking down municipal laws regarding 2A matters.
