Free NFA Gun Trust
- We offer a free NFA Gun Trust (a $250 value) to all customers which essentially establishes a joint ownership scenario in which you can legally share your silencer with designated others (as well as determining who will inherit your silencer). This lets others use your silencer.
- We do all the ATF paperwork which helps ensure you completed the gun trust correctly so ATF does not reject. We have completed over 15,000 silencer to gun trust transfers and counting! LEARN MORE
In the event you need you rifle barrel threaded to accept your new silencer, we will take care of that as well through our Threading Central. LEARN MORE
