Fwiw, I also just received a Tonys mil-spec Fiberlite CAR stock. Quality and fit looks fine. 5 position buffer tube. Weighing it as a complete assembly(buffer, tube, spring, endplate, stock) was 14oz. Compared to a std carbine commercial buffer assembly using a std relatively light M4 stock, was exactly 101gms(3.56oz) difference between the two.
