ATF Released Proposed Rules For Unfinished Receivers and Frames U.S.A. –-(Ammoland.com)- The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) released new proposed guidelines on unfinished firearms receivers and frames. As AmmoLand News reported back in November, the Biden transition team met with Acting ATF Director Regina Lombardo to get the ATF’s top priorities. The top brass at the ATF cited unfinished firearm receivers and pistol braces as their top two priorities. President Biden then promised swift action on firearms. Biden’s Vice President, Kamala Harris, is openly hostile towards the Second Amendment. She believes that the right to bear arms only applies to a state-run militia.
