A pre-drilled hole is included for pin and weld applications letting a gunsmith permanently attach the device for a compliant barrel length. The black phosphate finish matches most factory and aftermarket AR-15 finishes keeping the rifle s appearance consistent. Note that a crush washer is not included and should be sourced separately for proper timing and index.
