George, I would look at the folding adapter to use the current brace (starts around 6:00) : youtube.com/watch?v=uRiBoiD2-MI -------------- Cheers and stay safe!

George, they make adapters so you can use the existing buffer tube and stock. For some reason it won't let me share the one I was trying to recommend. Just Google AR-15 folding brace adapter and you will have plenty of options. That would be your best option for a folding brace. Hope this helps.
