Smoke Composites makes the lightest stock available for your carbine or rifle. There is absolutely nothing lighter than these stocks. They are made of carbon fiber and very strong. The stock also IS the buffer tube which means no extra weight of a buffer tube is needed. Each stock comes with the castle nut and a carbon fiber end plate. There are 4 versions of the stock. Carbine closed, Carbine open and for longer length of pull, Rifle closed and Rifle open. The rifle length stocks include a spacer for using a carbine buffer spring. Optional additions are a Magpul butt pad (which must be ordered with the stock since they get made to fit together) and a carbon fiber cheek riser (Sold as a separate addition).
