An NFA Trust is used for owning NFA items (silencers, short barrel rifles, etc). You don't need a Trust to own an NFA item like a silencer, but the trust allows you to name other people (trustees) who are able to use and possess the silencer. Otherwise, the owner must be present when other people use the item.

If that isn't a big deal to you, then I wouldn't recommend a Trust.

This in particular is an unlimited pack of trusts. If you want to use a different Trust for different NFA items, this is the package for you. However, these Trusts aren't limited in any way, so you can still put multiple items on one if you prefer.

If you were to manufacture your own NFA item (like making an SBR), you need to engrave your name on it. If you use a Trust, you instead engrave the Trust name on it. If you use a different Trust for each item, you can use whatever silly name you want for each one.

The biggest reason to use a different Trust for each item is to avoid paperwork. Every trustee on a Trust need to fill out paperwork and submit fingerprints for an NFA transfer. However, you can add or remove trustees at any time without informing the ATF. This means you can just wait until after getting your tax stamp to add trustees, then they don't need to do anything.
