DSG's STR Mil-Spec Stock Kit includes a MAGPUL STR Mil-Spec diameter buttstock, DSG's 7075, dry film-coated, mil-spec diameter receiver extension*, latch plate, nut, buffer spring, and carbine buffer.
*The DSG Mil-Spec AR Carbine Receiver Extension is a 6 position Mil-Spec diameter buffer tube made from 7075 aluminum. Manufactured in the U.S.A. and coated with dry film lubricant. Fits all Mil-Spec diameter stocks and is one of the highest quality 7075 tubes we have seen on the market.
Note: Dry film coatings are used for maximum lubricity on-duty use weapons. The finish will show handling and use marks by design. The dry film used on our DSG receiver extensions is similar to the coatings used on original USGI magazines but darker in color.
