G6R: Leak Down Barrel

If your marker has an air leak down the barrel. Check the items below and reference the manual as needed.

  • Ram: Remove the ram (pictured in the slideshow above) and inspect the o-rings for damage and replace if needed. Remove any dirt or lube from the ram and apply a small amount of Dow55 to the o-rings.

    • Front ram o-ring: 006 (Dura 70)

    • Rear ram o-ring: 011 (Dura 70)

  • Poppet: Remove the poppet (pictured in the slideshow above) and inspect the cup seal portion for any nicks or damage that would cause it not to seal correctly. If damaged, replace the poppet. Next, check the o-ring and replace if needed. Lube with Dow55. 

    • Note: The cupseal is the white delrin piece on the front of the poppet shaft that looks like a plug.
