A Florida lawmaker has introduced a bill in the U.S. House of Representatives to bar the government from banning any ammunition in the United States that doesn’t already face restrictions.

Congressman Thomas Rooney, a former Army JAG Corps officer and official in Florida Gov. Jeb Bush’s administration, introduced the “Protecting the Second Amendment Rights Act of 2015” in the House last week. The simple language of the bill says that “no entity” of the U.S. government may “restrict or prohibit the manufacture, importation or sale in the United States of any ammunition that, as of the date of enactment of this section, is not subject to the restriction or prohibition.”

The bill was introduced in reaction to a Bureau of Alcohol, Tobacco, Firearms and Explosives proposal to ban the popular M855 AR-15 round which it says violates restrictions on “armor-piercing” pistol rounds mandated by the 1986 Law Enforcement Officer Protection Act.

“The Obama Administration’s proposal would unilaterally strip law-abiding hunters and sportsmen of their Second Amendment rights,” Rooney said in a statement. “Congress has made its intentions clear that this ammunition is for sporting purposes and should not be restricted. We cannot and we will not stand by while the Obama Administration tramples on the Constitution, the rule of law, and the Second Amendment rights of hunters in my district and across the country.”

The bill has 13 co-sponsors, including veteran Texas Republican Rep. Pete Sessions, North Carolina Republican Rep. Walter Jones and Florida Republican Rep. John Mica. The bill was referred to the House Judiciary Committee. It is unclear when the bill will face a vote.
