Document type Title and Description
Regulatory 2025-1: Importing Dual-Use Barrels [PDF - 305.19 KB]

ATF has determined that federal firearms licensees may lawfully import “dual-use” firearm barrels—barrels that may be used on both sporting and non-sporting firearms—under 18 U.S.C. § 925(d)(3) if, at the time imported, there is an identified firearm sporting configuration for the barrel. Importation may be approved regardless of whether a barrel had been previously configured on non-sporting, military surplus, or National Firearms Act (NFA) firearms. Further, once the barrel is in the United States, ATF has determined that nothing in the statutes prevent a dual-use barrel from being used to assemble a sporting, non-sporting, or NFA firearm, provided assembling such firearm complies with 18 U.S.C. § 922(r) (assembly of a semiautomatic rifle or shotgun) and the NFA, 26 U.S.C. chapter 53, as applicable. This Ruling supersedes a November 2005 ATF Open Letter on dual-use barrels.

Regulatory 2025-2: Importing Training Rounds [PDF - 362.31 KB]

ATF authorizes the importation of certain marking rounds (“training rounds”) because these training rounds do not meet the definition of “ammunition” as defined by the Gun Control Act of 1968, 18 U.S.C. § 921(a)(17)(A). These items are not designed for offensive and defensive combat and are not “designed for use in any firearm.” Similarly, training rounds are not regulated by the Arms Export Control Act because they are not designed for use in any “firearm” as defined in the permanent importation regulations implementing that statute. An importer of training rounds that are not designed for use in any firearm may import the rounds without submitting an ATF Form 6, Application and Permit for Importation of Firearms, Ammunition and Implements of War (Form 5330.3A). Note, however, less-than-lethal ammunition, which is distinct from training rounds, is generally considered ammunition. This Ruling only applies to training rounds that are not designed for use in any firearm.
