GrovTec Suppressor Alignment Rod – .308 / 7.62mm
The GrovTec Suppressor Alignment Rod (GTHM364) is an indispensable insurance policy for any NFA enthusiast or professional armorer. Designed to verify absolute concentricity between the rifle bore and the suppressor baffles, this precision instrument is your primary defense against catastrophic baffle strikes. Machined from ground O1 tool steel with a durable black oxide finish, the GTHM364 is engineered to a strict straightness tolerance, providing a definitive visual "go/no-go" gauge before you pull the trigger on a newly suppressed build.
With an overall length of 15 inches, this rod is optimized for both precision bolt-action rifles and standard MSR platforms chambered in .308 Win, 7.62x51mm, or .300 Blackout. The procedure is simple: ensure the firearm is unloaded, insert the rod through the suppressor into the bore, and inspect the exit hole. If the rod is perfectly centered within the suppressor's end cap, you are clear to fire. Whether you are installing a direct-thread can or a new QD muzzle device, the GrovTec Alignment Rod protects thousands of dollars in suppressed hardware and months of NFA wait times.
Pro Tip: Always verify alignment every time you move a suppressor between hosts or install a new muzzle device. Thread shoulder variations can lead to misalignment even on "factory" barrels.
