Kit includes B5 Systems Enhanced SOPMOD Mil-Spec diameter buttstock, DSG's 7075, dry film-coated, mil-spec diameter receiver extension*, latch plate, nut, buffer spring and carbine buffer.
The SOPMOD buttstocks were originally developed by NSWC-Crane for use with SOCOM's. SOPMOD Special Operations Peculiar Modification M4A1 carbines. B5 systems, a well-known defense, and an aerospace contractor were selected in 2009 to supply the US Army with SOPMOD stocks. These quality stocks are now available on the commercial market.

Improved cheek weld for a better shooting position.
Watertight battery storage compartments.

*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.
