National Gun Trusts is GREAT! If you are going to get a gun trust, they make it super easy to understand. Plus, the added benefit of being able to change your trust whenever you want at no added cost is great! They offer a ton of ATF form examples and even videos to show you how to fill everything out and what needs to be done whether you are doing an SBR, Suppressor, or full auto. They have full walk-throughs on how to do everything. They also offer fingerprint cards, electronic finger-printing services and passport photo services. They provide everything you might need to provide to the ATF.
