Quick Installation Summary
Always follow safe firearms-handling practices. Ensure the firearm is unloaded before installation.
- Thread the flash hider and timing nut fully onto the barrel until they contact the shoulder.
- Back off and rotate until ports are roughly where you want them, then back the device off 10–20° from final timing.
- Hold the flash hider in place and bring the left-hand timing nut up against the barrel shoulder to lock timing.
- Using a wrench on the flats, rotate the flash hider into final timing and torque per instructions. Verify timing and POI.
- If pairing with a Plan B → HUB adapter, install the adapter before attaching the suppressor.
