The SureFire Bore Rods are intended for concentricity check prior to firing suppressed on a new platform. The rod most closely represents the bullet flight path and will show any issue of alignment, if present. Recommended to verify barrel to adapter to suppressor alignment, for any new build or any previously unshot setup.
This model is compatible with your 5.56 NATO firearm.
