PROFESSIONAL INSTALLATION RECOMMENDED
- Shouldermount muzzle devices index against the shoulder of the barrel
- Facemount muzzle devices index against the face of the muzzle and will require a facemount shim kit for timing
- For facemount devices, we recommend the use of an alignment rod for installation by a certified professional to ensure the facemount shims are stacked properly and do not make contact with the projectile exiting the muzzle
- Multiple shims can be used to achieve proper timing
- We recommend 30-40ft/lbs of torque along with Rocksett applied to the threads
- Improper installation may result in damage to the device and/or the suppressor as well as potential injury to the user
