Frequently Asked Questions

Is it worth buying one?
Yes. A check rod from any vendor helps eliminate costly baffle strikes and damage. Some people can eyeball it and be totally comfortable with it.

What if my check rod contacts the edge of my can? What's wrong, and could it be off center?

• Remove the suppressor, clean the threads and face of your barrel and can, and reinstall to the manufacturer's specs.
• If you are using an adapter or shims, inspect them for damage or cupping, which can cause tolerance stacking.
• Cheaper imported barrels may have threads that aren't concentric, or a barrel face that doesn't sit flush.
• Modern barrels are generally within spec, but check yours anyway as added insurance.
• Check the rod itself: roll it on a clean, flat surface such as glass, marble or granite. It should roll smoothly. Any bouncing means the rod may be bent.
• Reach out to a shop skilled in machining or suppressor-grade threading. Here in CT we recommend JoJo's Gunworks.

What is the recommended length of an alignment rod?
Typically 15 to 17 inches, which accommodates most firearm and suppressor setups. NDZ makes check rods in 16" and 12" lengths.

Can one rod cover multiple calibers?
Yes, within closely related calibers. For example, a .30 caliber rod works for .308, .300 BLK and 7.62x39. Always match the rod to the caliber you are using.

How do I use it?
Unload your firearm, mount the suppressor to the manufacturer's specs, carefully insert the rod through the suppressor into the barrel, and visually confirm equal spacing around the rod at the base of the suppressor’s muzzle.
