- Hold the brake in place and tighten the left-handed nut against the barrel shoulder to lock timing position.
- Using a wrench on the flats, rotate the brake forward into final timing and torque to at least 20 ft-lbs for secure lockup.
- When using a Plan B → Hub-Mount adapter, install it per manufacturer instructions before attaching your suppressor.
