Blue Force Gear A2B-BK VCAS Buttstock Adapter - AR-15 Stock Mount

The Blue Force Gear A2B-BK VCAS Buttstock Adapter transforms standard AR-15 rifle buffer tubes into mounting platforms for tactical stocks and accessories. This precision-machined adapter eliminates the need for permanent modifications while providing a rock-solid foundation for enhanced weapon configurations.

What Makes This Different

Unlike basic stock adapters that rely on friction fits or clamp mechanisms, the VCAS Buttstock Adapter uses Blue Force Gear's proven mounting system with steel hardware and aircraft-grade aluminum construction. The adapter maintains zero movement under recoil while allowing quick stock changes without tools. Standard adapters often introduce play or require permanent alterations to the host weapon.
