There are two tubes, one barrel nut and one locking ring. both tubes fit the barrel nut and locking ring. The fiber glass tube is an older ArmaLite Original version but I drilled some holes into it to bolt on some rails. The aluminum one was the donor for the rails.
First $80.00 gets it all, O.B.O.
