In a national revolt that rivals the Boston Tea Party, all but a handful of gun owners targeted by President Joe Biden have decided to protest the administration’s sweeping rule to regulate one of the most popular and freely owned firearms ever made.

The owners of just 0.6% to 1% of AR-15-style pistols have complied with a May 31 deadline set by the Bureau of Alcohol, Tobacco, Firearms, and Explosives to register their firearms. By failing to do so, the owners of an estimated 20 million to 40 million guns could face 10 years in prison, a $10,000 fine, or both.

According to ATF spokesman Erik Longnecker, “As of June 1, 2023, ATF received 255,162 applications for tax-free registration.”
