The FAB Defense Mako GL-CORE Skeleton Stock, Black (FAB Defense part no. FXGLCOREB) is the newest addition to FAB Defense’s line of AR15/M4 buttstocks, built around an integrated cheek rest and an ergonomic, rubberized buttpad for quick, comfortable shouldering. An interchangeable tube adapter gives the GL-CORE a tight fit on both Mil-Spec and Commercial buffer tubes, while a compact, no-snag profile keeps it from catching on gear or webbing. Two integrated quick-detach sling swivel sockets and a lever that won’t open accidentally round out a stock built from durable, lightweight fiberglass-reinforced polymer composite.
