According to the final rule, gun owners who possess braced firearms will have to destroy, reconfigure, register, and turn in their firearms to ATF, or face NFA violations which include $250,000 in fines and a hefty prison sentence.

This rule will have some of the most wide-reaching impacts nationwide compared to other ATF administrative rulemaking actions. In comparison, ATF's bump stock rule was estimated to have affected 520,000 Americans, whereas this pistol brace ruling affects 80 times more law-abiding citizens.

In response, the No Compromise Alliance sent a letter signed by notable firearms industry companies to Congress.
