The House on Wednesday passed a sweeping gun reform bill that would raise the minimum age to purchase an assault rifle in the U.S. from 18 to 21, even though the legislation doesn’t stand much of a chance of passing in the Senate.

The bill, called the Protecting Our Kids Act, would also bar the sale of large-capacity magazines and institute new rules that dictate proper at-home gun storage. The chamber approved it in a 223-204 vote.

The House earlier voted by a 228 to 199 margin to include the purchasing age provision — under heavy scrutiny after two recent massacres carried out by 18-year-olds — in the broader bill. Democrats backed the proposal in a mostly partly line vote, but it drew a small group of Republican support.

Another component of the legislation, called the Untraceable Firearms Act, would bolster regulations around so-called ghost guns, or those firearms without a serial number. It is far more difficult for law enforcement to track ownership and possession of firearms that lack serial numbers.
