The B5 Systems Enhanced SOPMOD stock is a proven design for AR-15 platforms, officially selected by the US armed forces. It fits all Mil-Spec diameter buffer tubes (receiver extensions) and offers an ergonomic, stable cheek weld, eliminating play and slippage.
The non-slip cushioned buttpad keeps its position on the shoulder, the SureGrip lock ensures reliable locking on the tube and the two side storage compartments let you store batteries or small accessories.
