Questions and answers

Under current federal policy, yes. In 2024 the Supreme Court and a federal court in Texas ruled against treating these kinds of triggers as machine guns. In May 2025 the Department of Justice agreed to stop treating forced reset triggers as machine guns.

Some states ban them under their own laws, and we don't ship to those states. Read the full explanation.

No. Every trigger we sell is semi-automatic. The gun fires one round, then the trigger has to reset and be pulled again before it fires another.

No. Our parts aren't firearms or NFA items under federal law, so they ship straight to you. You still have to be 18 or older, and the part has to be legal where you live.

No. Altering a trigger so it fires more than one shot per function of the trigger can make it a machine gun under federal law, which is a felony. Modifying a part also voids the warranty.

Trigger parts ship to 32 states. See the list. The M+M micro red dot ships to all 50 states. 30-round AK magazines ship everywhere we ship triggers except Vermont.

Either your state bans these parts or we think its law is unclear enough that we won't take the risk. We don't make exceptions, including for orders shipped to a friend or a different address.
