Shim Kit

CORRECT INSTALLATION

Shim Kits are used to properly time muzzle devices, primarily muzzle brakes. While most flash hiders do not need them, some users prefer to time the prongs to a specific orientation.  Shim sets do not need to be brand-specific, and any muzzle device can use any manufacturers shims.  Some brands offer slightly different sizes or minor features, but there are no compatibility issues.
