A court order that struck down regulations on firearm suppressors and certain guns took effect Thursday after the U.S. Justice Department did not file an appeal before a seven-day deadline set by a federal judge in Texas.

The ruling allows people to purchase silencers, short-barreled rifles, short-barreled shotguns and certain other firearms without registration, while also removing an extra layer of background checks.

The order benefits parties that brought the lawsuit, including some dealers based outside northern Texas, but it is not a national injunction.
