My Son bought this factory DD pdw with a folding brace. During the "a brace is an unregistered SBR" thing he removed the brace and buffer tube to avoid any legal issues. In multiple moves,he lost the parts. He is currently deployed and I would like to have it fixed for him when he returns. Can you pistol guys point me to what I need?? Thanks in advance.

PSA has a mother's day special on the SBA3 brace. This is my favorite and one of the most popular braces for AR pistols.

Here's a link: https://palmettostatearmory.com/sb-tactical-sba3-5-position-adjustable-arm-brace-buffer-tube-not-included-black-sba3x-01-sb.html

You'll also need to purchase a buffer, buffer tube, and buffer spring. I would grab an H3 buffer an a F R T -or- S u p e r   s a f e t y  trigger... Your son will thank you.

So it just takes a standard buffer tube? Nothing proprietary to the folding par?

Yes. I believe it accepts a standard buffer tube. I bet a Geissele DDC buffer tube would look awesome.

There is also a little "adapter" That fits in the rear of the BCG, to work with the folder. This comes with the DD.

If you are going to put the folding capability back you will need the other half of the folder and bolt carrier plug extension or replace the fold part your currently have with a complete unit.  Otherwise you can remove the folding part that is there and just install a new receiver extension, castle nut, end plate, buffer spring and buffer, and brace of your choice.

As I suspected. Can you point me to a complete folder or parts? Who makes it?

that looks like the receiver half of the LAW Tactical folding adapter. If he lost the parts, you might likely need a whole new assembly.

You already have the folding mechanism installed. That's the Law Tactical Folder. Watch some youtube videos to understand how it works. You appear to be missing this piece which plugs into the back of the BCG: https://www.lawtactical.com/bolt_carrier_extension_p/repbceg3m.htm

At that point, all you need is a "normal" buffer tube setup (properly called the Receiver Extension) that any AR would have. It all threads into the rear of the folding mechanism. You can get a complete kit that includes the brace and the full receiver extension kit. Here is one example. I have not vetted this retailer at all, so perform your own due diligence, but this kit would contain all the necessary parts: https://davidsondefense.com/sb-tactical-ar-15-pistol-stabilizing-brace-w-complete-buffer-tube-kit

It is missing half of the folding assembly that the receiver extension, castle nut, and end plate attach to.
If OP does not know where the parts are he should just order an entire new folding assembly or drop the folding assembly all together and just attach a new receiver extension setup to the lower receiver.

+1 Too many missing proprietary parts that I don't think Law Tactical will sell separately.  You're better off buying a new Law Folder or (doing like i did) going with a new complete PDW brace setup like the HBPDW https://dirtybirdusa.com/products/sb-tactical-hbpdw-5-56-pistol-stabilizing-brace-black/  currently on sale for less than the price of a Law Folder and it includes the brace, buffer, buffer tube and buffer spring.

Thanks everyone for your help. The missing parts are long gone,so a new one is in order.

Your son is deployed. Ask nicely, and be willing to pay, and it would not surprise me if they made the parts available for you. They know your son buys their parts, sometimes loyalty does go both ways.

Or simply purchase a new one, and take it apart too. Consider it a life lesson. Every time I relearn this life lesson, I eventually find the rest of the parts.

The receiver half of the folder is already installed. If you could buy the rest of the parts, including the hinge pin, it would simplify restoring that weapon.
