Product Description The SureFire Suppressor Bore Alignment Rod (SF-ROD-6) is a precision gunsmithing tool engineered to ensure proper concentricity along the bullet flight path before the first round is ever fired. Designed specifically for 6mm bore calibers, this precision-machined, heat-treated stainless steel rod most closely represents the actual bullet flight path and will reveal any misalignment between the barrel, adapter, and suppressor. SureFire recommends that operators verify barrel-to-adapter-to-suppressor alignment on any new build or previously unshot setup, and the SureFire Bore Rod is the most effective and accurate way to confirm it. Simply select the corresponding rod for your caliber rifle or carbine and get it right the first time.
