President Donald Trump has begun the process of overturning gun-related policies issued under his predecessor, Joe Biden.

As a candidate, Trump said, "Every single Biden attack on gun owners and manufacturers will be terminated on my very first week back in office, perhaps my first day."

Trump signed an executive order Feb. 7 that said within 30 days, the attorney general "shall examine all orders, regulations, guidance, plans, international agreements, and other actions of executive departments and agencies … to assess any ongoing infringements of the Second Amendment rights of our citizens, and present a proposed plan of action to the President."

The order specified that all presidential orders from Biden's tenure and Biden-era rules from the Justice Department and the Bureau of Alcohol, Tobacco, Firearms and Explosives would be reviewed. The order also requires examining stances the federal government has taken in ongoing Second Amendment cases.

The order is "widely expected" to affect several policies, said Mark Oliva, managing director of public affairs with the National Shooting Sports Foundation, a firearms industry association. According to Oliva, they include: 

• ATF's 2021 "zero-tolerance policy," which requires revoking gun dealers' licenses if they have committed one of five violations, including selling a gun without a background check or falsifying business records. Gun rights supporters have said this has caused an unnecessary spike in revocations.

• ATF's "engaged-in-the-business" rule, which defines what constitutes a firearms business, including that someone "repetitively resells or offers for resale firearms" within 30 days after purchase and that "posts firearms for resale, including through the Internet" or repeatedly rents "a table or space at a gun show." Critics have said that the rule has affected nonprofessional firearms collectors.

• ATF's "pistol brace rule," which addresses stabilizing devices for pistols, an accessory that can be helpful for shooters with disabilities. The rule classifies braces that reach the shoulder as short-barrel rifles, which critics have said imposes undue burdens, including special registration requirements, longer waiting periods and higher tax rates.

• ATF's "frame and receiver rule," which tightens requirements on guns assembled from kits, including requirements for manufacturer licensing, inclusion of serial numbers and record-maintenance standards, plus wider background check enforcement.

Trump's executive order didn't officially start the rulemaking process to overturn these provisions, but it's only a matter of time, Oliva said.

"The rules haven't gone 'poof,'" he said. "But, you could liken it to President Trump having just lit the fuse."
