The B5 Systems Enhanced SOPMOD Stock (brand part number SOP-1076) is an adjustable AR-15 buttstock finished in Coyote that carries forward the Crane NSWC-designed SOPMOD profile with a set of military-driven upgrades. B5 Systems built in color-matched steel hardware, a one-piece anti-rotation QD sling mount, and a non-slip cushioned buttpad, all made from MIL-SPEC materials and finishes.
