SureFire Bore Alignment Rod Features The SureFire Bore Alignment Rod is precision-machined from heat-treated stainless steel to most closely represent the bullet flight path in the 6.8 caliber bore providing the most accurate possible verification of concentricity between the barrel suppressor adapter and suppressor prior to first firing on any new build or previously unshot configuration. Simply inserting the rod through the mounted suppressor on an unloaded weapon reveals any alignment issues visually by checking for equal space between the centered rod and the suppressor bore identifying potential baffle strike risks before they can occur during live fire. The 6.8-specific caliber sizing ensures accurate concentricity verification for 6.8 caliber rifle and carbine platforms without the imprecision of a universal or multi-caliber rod. The pre-fire suppressor alignment tool is recommended for any new suppressor build or previously unshot setup across 6.8 caliber rifles providing a simple fast verification step that protects both the suppressor and the shooter from the consequences of misalignment. Heat-treated stainless steel construction delivers long-term dimensional stability and corrosion resistance for a bore rod that maintains its accuracy across repeated use on multiple platforms. A caliber-specific rod for 6.8 ensures the most accurate alignment check available for shooters running 6.8 caliber suppressors across semi-automatic and bolt-action rifle platforms.
