We are going to be away for Season . The shop won't be completing orders for that time. Thank you for your understanding.

FX Harmonic Touning



This is a 3D printed part that closes the gap between the tank and the barrel and helps with the harmonic tuning by eliminating the up and down barrel vibrations after every shot. Testing shows more consistency and better groups.


Install at the front end of the tank as shown in the picture.

After installing, re-zero MUST be done to the scope because the POI will be shifted upward.
