Product Description Get it right the first time with the SureFire Bore Alignment Rod for 5.56mm caliber. This precision-machined, heat-treated stainless steel rod is the SureFire-approved tool for verifying proper suppressor alignment before firing a single round. By most closely representing the bullet&';s flight path, the rod immediately reveals any misalignment between the barrel, adapter, and suppressor. SureFire recommends that operators confirm barrel-to-adapter-to-suppressor alignment on any new build or previously unshot setup, and the Bore Alignment Rod is the most effective and accurate way to do so. Simply insert the rod through the mounted suppressor of an unloaded weapon - equal spacing between the bore of the suppressor and the centered rod confirms proper alignment.
