The B5 Systems SOPMOD Gen 2 is a faithful recreation of the USSOCOM SOPMOD stock used by US Special Operations units, updated with modern materials and production tolerances. The extended rubber butt pad reduces felt recoil while providing a non-slip surface, and the cheekweld on the side of the stock is notably higher than standard carbine stocks for easier optic use. Internal storage compartments accommodate batteries or small cleaning supplies. A large QD socket is integrated on both sides. The stock fits mil-spec buffer tubes and is built from fiberglass-reinforced polymer that won't crack under impact or in cold weather. Often cited as the best combination of function and ruggedness in a fixed-position carbine stock.
