From The Federalist:

Out of the myriad options a Biden administration will have to infringe on our constitutional protections, which will they choose first? Based on my experience with clients and the Bureau of Alcohol, Tobacco, Firearms and Explosives (AFT) as a firearms attorney, some recent news events, and a bit of firearm-industry intuition, I think the first things a Biden administration will do regarding guns if given the chance are:

• Banning pistol braces
• Banning homemade firearms/80 percent receivers
• Banning online firearm and ammunition sales

Shortly after the first bans, and if he has the help of the Senate, the next gun control measures will likely be:

• Banning “assault weapons”
• Banning “high capacity” magazines
• Requiring universal background checks
