Lower recievers.
Get 'em now.
Future Bans will have to exclude and grandfather previously made rifles.
Or they will have language that prohibits ALL rifles of a certain make/profile.
If they blanket Ban, or expect registration, stand the hell by.
The expired Ban was a lesson, and an experiment in what folks will tolerate.
Stripped lowers are cheap right now.
I resent the paranoia, but it has been proven to be a real situation that has to be considered.
Lowers, Magazines, then components.
Invest with an eye on the future.
