Not sure if this is legal in this forum but here it goes, I saw an adapter for the AR platform that screws in the lower receiver and then the buffer tube goes in the adapter. You cab press a button on the side of the adapter and it allows you to fold the buffer tube and stock around to the side of the gun. I want to know who makes these. I have looked online and was unable to find anything. Any help is appreciated. Thanks in advance. P.S. They were sold at the gun show last weekend in Tulsa.
