This is a used RRA 6 position stock. It is green in color. I have had it for a while and only put it on a couple of guns. I tried to make it "post ban legal" by drilling a hole into the top hole of the stock when it was fully extended, so there is about a 3/8" hole in the aluminum part(buffer tube is what it is called I think). Keep that in mind when considering this stock. Comes with spring, plate, and buffer. Since it has that hole in it, I will take $35 shipped. I am going to get a black telestock so I have no need for the green one anymore.
