- As of October 9, 2026, ATF isn’t enforcing the Form 1 requirement federally.
- It’s still a firearm under federal law. You can’t make them to sell without a license.
- Several states ban homemade suppressors. Check yours first.
- Alignment and quality matter. A bad build can cause a baffle strike.
Not legal advice. Always check your state’s laws.
