As we’ve previously discussed, the rules, regulations and laws surrounding silencers is tricky at best and downright scary at their worst. The fact that a single baffle is considered a silencer within itself is still, well, baffling. However, these are the laws here in the US, and until we get them changed or repealed, we all have to follow them or face the repercussions. Apparently, one Ohio man decided to push the boundaries of the law and caught the attention of the ATF when he was selling muzzle brake variations on eBay.
Another grim reminder that ATF does not work based on logic.
I found a copy of one of the insane shoelaces string = machine gun part letter. Enjoy the madness.
