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.

    338 check rod

    Published by Jethro on 12th Dec 2023

    As a prototype machinist for a large Engineering Company machinist I use high precision tools on a daily basis. Good tool aren't cheap, the only way I could attempt to find a defect would be to use a CMM. My 0.0001" mic's were spot on the engagement with the barrel of my rifle was like glass on glass. It's a piece of mind to by a check rod, 800 can or 60ish dollars. It's not worth rolling the dice and gamble on you rifles threads being concentric to the bore, then the muzzle device and then the cans threads. That called tolerance stacking and that's always stupid

    Alignments rods

    Published by Chris Townson on 29th Sep 2023

    These rods are expensive but worth the money. I have several firearms that I switch my bushwhacker 46 around on ( excellent supressor by the way) and checking alignment is critical. I have already found that some other companies adapters are not as good of quality as griffins and I have found alignment issues. Without theses rods you would find out the hard way.

    Alignment Check Rod

    Published by Tom Demaree on 10th Jul 2023

    Use of this tool should be made mandatory to ensure proper attachement of the suppressor to the pistol. I use alignment check rods on my 9mm and .45ACP pistols. Do not, repeat, DO NOT fire that first shot without checking the alignment!
