"In May 2018, the Trump administration proposed revising revise the ITAR regulations. The move for regulatory reform actually began under the Obama administration, but the proposed reforms were never published. Now they have been. Export controls for many ordinary firearms and accessories will be removed from the ITAR list. Exports of such items will instead by controlled by the Department of Commerce. Among the items remaining under the ITAR system are automatic firearms, firearms of greater than .50 caliberr, magazines with more than 50 rounds, and sound moderators (a/k/a "silencers"). Non-automatic firearms of.50 caliber or less will no longer be covered under ITAR; among the firearms no longer under ITAR is the semiautomatic AR-15 rifle, the most common rifle in American history. Its typical calibers are .223 and .308--well under the new .50+ caliber rule.

"Accordingly, the government defendants revisited the Defense Distributed case. If a particular arm (e.g., the AR-15) is no longer part of ITAR, then it would be illogical for ITAR to be applied to instructions for making the arm. Under today's settlement agreement, plaintiffs and others may freely publish 3D printing instructions for firearms that are not covered under ITAR. Restrictions on distribution of 3D printing information for items that are still under ITAR, such as machine guns or rifles over .50 caliber, remain in place."
