So I see you can do the Eform but my question is can I do the eform using my trust? I assume I would need to send a digital copy in with it, is this correct?
and I have 2 pistols with different length barrels that I want to use can you put them all in the box or pick one type of thing? Is there anything im missing?

Upload electronic copy of trust.

You have to pick one of your uppers, submit that caliber/barrel length/OAL. Then you can use whenever one you want after you initially build it to those specs.

And if you haven't seen it, the Visual Guide should answer most of the EForms questions.

is it really that easy??? pick one and go with it!!  I did read I can engrave my info on the barrel now too so this would help a bit as I could engrave all the uppers....

my brain hurts doing all of this

the eform guide is what made me ask the silly questions....its early and only had 3 cups of coffee so far!

The Form 1 is for building one specific rifle.  After it's built it can change, but your application is to build it as the form is filled out.  Pick the upper with the caliber and barrel length you want to use for the form.  When the form is approved assemble the rifle with that upper, after it's assembled you can swap the other upper on anytime you want.



Make sure you put the total length of the firearm with the stock extended, so you will need to know what stock you are using and measure with it extended.



I would recommend scanning a pdf copy of your trust, make sure it is legible, but it's easiest if you keep it under 3 mb.  Mine came in under 1mb.



When filling out the form use the model and serial that is on your rifle, if someone has entered a similar model, don't automatically use what is available - if it doesn't exactly match what your receiver has printed on it then don't use it.  You can attach a picture of your lower that shows the correct original manufacturers markings if you want.

       
 

If you engrave the upper, you have to engrave every upper you want to use.  It's much easier to just engrave the lower.

I have an engraver at work and plan on 2 uppers.....would it not be better to do the barrel so I am not stuck with just one lower I can use?

You can only use the registered lower as an SBR. The lower is the firearm, you can swap different uppers onto the registered lower, but the lower is the SBR.

oh ok....I guess I was looking for a way to not mark a lower.

Iirc you can mark the barrels/uppers, but you will need to mark both of them along with any future uppers you want to use.

Correct. It must be marked when in SBR configuration. So, if you don't mark the lower, every upper/barrel you use would have to be marked.

Just mark the lower and be done with it. You can do something discrete like around the trigger hole or on the front of the magwell. Or, do like most if us, and just mark it on the right side over the trigger pins, or on the side of the magwell. There's no real market for used lowers, so don't avoid engraving it just because you think it would be harder to sell down the road.
