From Ammoland:

Firearms Policy Coalition today issued the following statement regarding the ATF’s “Open Letter to All Federal Firearms Licensees” regarding its classification of some “forced-reset triggers” (FRTs) as “firearms” and “machineguns” as defined in the National Firearms Act (NFA) and Gun Control Act (GCA):

This latest effort by the ATF to punish and stoke fear among peaceable people who purchase protected-arms components specifically designed to comply with federal law is further proof of the agency’s abusive overreach of statutory and constitutional bounds and a manic desire to expand its dominion. Furthermore, by being purposefully vague in saying it “intends to take appropriate remedial action,” the ATF adds to the unscrupulous nature of this action leaving sellers and owners unsure if they’ll be subject to abuse.
