"The 16,485 'missing' guns are likely a vast undercount of the total number of guns that disappeared from gun manufacturers in the last two and a half years," the report reads.
Acting president of the Brady Center Dennis Henigan said in a statement that the results are "shocking."
"Given the lethality of its product, the gun industry has a special duty to act responsibly," he said. "Instead, it has a scandalous record of carelessness."
The report comes at a time of unrest at the ATF, where two top officials resigned last week in the wake of a scandal involving a controversial anti-gun trafficking program.
The report goes on to claim that "weak" gun laws in the U.S. do little to stop firearms from ending up in the wrong hands.
"Despite the serious public safety risks created when guns are obtained by criminals
and other dangerous persons, federal laws are so weak that they do not require gun
manufacturers and dealers to maintain even minimal security or inventory controls," the report reads. Read the entire Brady Center report here.
