With the appropriate Griffin Armament Suppressor Alignment Check Rod, an end user or gunsmith can verify alignment of the chosen suppressor and mount with the desired host. Installation and use of this tool is simple and should prevent baffle strikes or any unexpected issues once you get to the range.

Griffin Armament has gone to great lengths to accommodate a wide variety of thread pitch and caliber options across our silencer mount and adapter products. This gives practically every end user who wishes to suppress their host the opportunity to do so! With this wide range of compatibility comes its own set of issues, the main one being silencer and mount alignment to the host firearm's bore. 

To use the Suppressor Check Alignment Rod:

  1. Properly mount your silencer to the host firearm
  2. Insert Suppressor Alignment Check Rod down bore of the silencer and into the host firearm bore until the end of the rod is flush with the end-cap of your silencer
  3. Observe alignment and confirm rod is positioned near the center of the silencer bore (refer to images above for examples of proper alignment and misalignment) 
  4. Host firearm may need to be rotated around bore to confirm alignment due to tolerance between the bore and check rod.
  5. If mount and silencer are in alignment, remove rod and enjoy your suppressed firearm!

If you are experiencing misalignment with a Griffin Armament suppressor, please contact our Customer Service department for assistance. We may be able to help, however it is important to note that some threaded barrels in the market are not cut with the needed quality to safely mount a sound suppressor. If your firearm exhibits this condition we suggest the use of Adco Firearms in Sylvania, OH for custom suppressor grade threading.

    Suppressor alignment rod

    Published by Phil Z on 25th Apr 2022

    Excellent product, perfectly crafted, shipped and received quickly. This identified a non-concentric barrel prior to using with a suppressor, helping me avoid a baffle strike. These are a must have for suppressor users. Will be getting more in different calibers. Thank you Griffin!

    This is a great way to make sure you do not get a baffle strike

    If you ever had a baffle strike because of a muzzle device that was put on incorrectly this is a good way to check your work .

    9mm Suppressor Alignment Rod

    Published by Eric on 25th Feb 2022

    The rod is machined to precision and fits snuggly into the barrel. I am quite confident my muzzle device is in alignment after using this rod.

    Alignment rod

    Published by Eric on 21st Feb 2022

    I recently built my first farm one suppressor at home. It was a really good idea to buy an alignment rod!!! More than likely would’ve had a baffle strike and if I did not. I had to shave off a little more on the last about four and a little bit more on the end cap… went and test it the next day and it was absolutely perfect worked great. Also you guys have the fastest shipping known to man I order and I get something 3 days later!! Thank you so much!!

    Extremely well made rods. Every suppressor owner should have one in each caliber they shoot suppressed. Package was sent fast and secure. Items were packaged great. I am highly satisfied.
