This will probably never fly but...
1) Do away with the current system of regulating fully automatic weapons entirely. (Tax stamps and Hughes ammd. included)
2) In place of aforementioned system allow manufacture and sale of full autos in the US, instead of tax stamp for each individual weapon have a federal permit that must be applied for (kind of like a CCW except w/ Uncle Sam instead of state).
