PROFESSIONAL INSTALLATION RECOMMENDED

• Shouldermount muzzle devices index against the shoulder of the barrel 
• Facemount muzzle devices index against the face of the muzzle of the barrel 
• If using shims with Facemount devices, you must use an alignment rod to ensure the facemount shims do not make contact with the projectile exiting the muzzle
• 30-40ft/lbs of torque along with Rocksett applied to the threads is recommended
• Improper installation may result in damage to the device and/or the suppressor as well as potential injury to the user
