(The Center Square) – A Biden-era rule placing greater constraints on millions of legal American gun owners could be struck down if newly introduced Republican legislation becomes law.

Companion bills introduced by Sen. Roger Marshall, R-Kan., and Rep. Andrew Clyde, R-Ga., would undo a 2023 ruling by the Alcohol, Tobacco, Firearms and Explosives (ATF) that classified pistols modified with stabilizing braces as short-barreled rifles and thus placed them under the National Firearms Act.

The action required all owners of pistols modified with stabilizing braces to pay a $200 fee, register their name with the U.S. Department of Justice and obtain federal approval to construct or transfer a short-barreled rifle or short-barreled shotgun.

“‘Shall not be infringed’ is crystal clear – and the Biden-era abuses of the Constitutionally protected rights of gun owners across the country need to be undone,” Marshall said in a statement Tuesday. “The SHORT Act takes a step toward rolling back nonsensical regulations that the National Firearms Act has placed upon gun owners.”

A 2021 report by the Congressional Research Service estimated that between 10 and 40 million stabilizing braces and similar components are in civilian hands. Supporters of the rule say it will increase safety.

Both the Gun Owners of America and the National Association of Gun Rights, who called the Biden-era rule unconstitutional when it was implemented, expressed support for the legislation.

“The SHORT Act is a long overdue step toward restoring the rights of Americans, freeing gun owners from the burdensome and outdated regulations of the National Firearms Act,” NAGR political affairs director Hunter King said. “By removing short-barreled rifles, shotguns, and similar firearms from egregious federal regulations, gun owners would be able to exercise their Second Amendment freedoms without oppressive government interference.”
