The federal government has announced a settlement of a case involving Rare Breed Triggers' forced reset triggers. This is essentially an out-of-court resolution, so it's far short of a Supreme Court ruling. That means a future ATF under a different administration could pursue any other maker of forced reset triggers. But ... it's better than nothing.
The ATF agreed to not consider Rare Breed's FRTs to be machine guns, and rare Breed agreed to not develop FRTs for handguns.
