PROFESSIONAL INSTALLATION RECOMMENDED
- Shouldermount muzzle devices index against the shoulder of the barrel and will require a Shouldermount shim kit for timing.
- 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.
