Class 3 Firearms, NFA & Destructive Devices FAQ
What does Class 3 mean?
It is everyday shorthand for items regulated under the National Firearms Act and for the dealers licensed to sell them. You will see it used interchangeably with NFA.
Why does an NFA purchase take longer than a regular gun?
Every NFA transfer needs federal approval before the item can be released. That timeline is set by the ATF, not by us.
How do I pick the right suppressor mount?
Match the mount system your suppressor uses, then match the thread pitch on your barrel. Check both against the product listing before you order from Class 3 Parts & Accessories.
Where can I find the current rules?
The ATF publishes the current federal NFA rules at atf.gov. State and local laws vary and change, so check yours before you buy. We cannot give legal advice.
