For optimal performance and safety, precise setup procedures are essential when installing your muzzle device and silencer. Begin by using an alignment rod to verify the correct configuration of the entire system, preventing any misalignment that could impact performance or safety. Before installation, ensure all surfaces, including the muzzle device and barrel, are thoroughly cleaned and free of debris or residue. Proper cleaning ensures a secure fit and optimal function. Once cleaned, torque the muzzle device to the barrel with a force of approximately 15 to 25 foot lb. Apply Rockset to secure the muzzle device firmly, ensuring it is square against the shoulder for a stable setup. Note that using this setup on a Q can will void your warranty, so proceed with caution if considering this option. When attaching the silencer to the muzzle device, double-check that the threads and tapers are clean and free from obstructions for a smooth and secure connection. Torque the suppressor to 10 foot lb, maintaining proper alignment throughout the process. By following these detailed steps, you can ensure a reliable and efficient setup. Once everything is in place, enjoy the enhanced performance and reduced noise levels that a properly installed silencer provides. 17-4 PH H900 Compatible with Atlas and Atlas XL Compatible with Plan B The Atlas adapter has exceeded the limit by approximately 0.05 inches Atlas XL adapter does not experience overrun Black nitride coating with a surface hardness of 67 HRC
