Not unless you pin that one too. Awesome, huh? (Unless it's a pre-ban lower of course.)
With that said, there are very few folding stocks that will work on an AR anyway. You'd need to do something about the buffer and buffer tube. Unless you went with a small caliber like .22 or maybe 9mm I don't think you could do it. (Someone will be along shortly to correct me if I'm wrong.)
