Quick Installation Summary

Always follow safe firearms handling practices. Ensure the firearm is unloaded before installation.

1. Thread the flash hider and timing nut fully onto the barrel until they contact the shoulder.
2. Back off and rotate until ports are roughly in the desired orientation, then back the device ~10–20° from final timing.
3. Hold the flash hider in place and bring the left-hand timing nut up against the barrel shoulder to lock timing.
4. Using a wrench on the flats, rotate the flash hider forward into final timing and torque per the instruction card. Verify timing and POI after installation.
5. If pairing with a Plan B → HUB adapter for hub-mount use, install the adapter before attaching the suppressor.
