The Sons of Liberty Gun Works Steel M-LOK QD Socket (brand part no. 4140SOCKET) gives an M-LOK handguard a dedicated, positive-locking home for a quick-detach sling swivel. Machined from steel and finished in QPQ (a black-oxide nitride process) for corrosion resistance, the socket is built to withstand the repeated insertion and removal cycles that a QD swivel goes through during hard training or duty use, where a worn-out or plastic socket can fail at the worst time.

Key Specifications

• Steel construction resists wear from repeated QD swivel insertion and removal better than polymer sockets.
• QPQ black-oxide finish adds corrosion resistance for hard use in the field.
• M-LOK mounting interface attaches directly to M-LOK-compatible handguards without an adapter rail.
• Positive-locking design keeps the QD swivel secured under recoil and hard use.
