Can I have a collapsible stock (just the stock, not mounted on a rifle)shipped to me and then take it to a gunsmith to have pinned or dose it have to be shipped directly to a FFL to be pinned?

Its not a regulated item until you have all the parts necessary to complete an "assault weapon". If its just the stock and buffer tube you are fine. If you have the rest of the rifle I would say no and have it shipped to the smith.

Check with the gunsmith as to how he wants to handle it.  He will want to do the assembly in a specific order so he has the stock pinned before it is on the gun.

Fixed that for you.

 

I know FFLs receive fully assembled rifles with unpinned stocks and pin them to the customer's desired size.

There are no cases on constructive possession under NJ AS law I know of. There are a few ways I think you could get around it but you're better off having it shipped to a FFL.

If you already know your size pin it your self.

Just get it size it and pin it. It takes more time getting out the tools than it does to do make it compliant.

FYI, 3/32" drill bit and a 3/32" X 3/4" roll pin. Have a nice day.

How would he pin it before installing the buffer tube and torquing the castle nut. Are there tools that will torque without catching three sides?

He can pin it, thread it on together, then torque it with that wrench.

Yeah but if you did that..you couldn't size it to your liking prior to pinning it.

Your FFL can possess "assault weapons". He/she will size it to your liking and pin it for you. At that point it is no longer an "assault weapon", and he/she will then transfer the rifle to you.

He has to have some idea. There's not that many positions

The nut tool is 10 on amazon or im sure someone here might let you borrow one. Drill a tiny hole, take a punch and hammer tap in slightly bigger roll pin.

Can be pinned Prior to installation.

Nice. I'll have to pick one of those tools up. The two I have go around 90 degrees more
