G6R: Frame Leak

If your marker is leaking from the frame. Check the items below and reference the manual as needed.

Issue:
Tank:
  • Be sure you're using a low pressure (or SLP) tank as recommended by Blast. 

  • Verify that your grip frame and body screws are all tight. This will help create a good seal. Reference page 13 of the manual

Grip Frame & Body Seal:
O-Rings:
  • Start by zeroing out your HPR and LPR regulators. You can do this be turning the adjustment screw (on the HPR and LPR) counterclockwise until it is flush with the bottom/outside of the reg. Next, air up your gun and check one of the following (Reference the manual if needed):

    • If your gun leaks with both regs zero'd, remove the front main body from the trigger frame and inspect the 3 body o-rings for damage and replace if needed. Lube with Dow55. If it doesn't leak, move on to the next step below. 

      • Grip Frame to Main Body Front: 014

    • If your gun didn't leak after zeroing out your regs, increase the pressure on your HPR by slowly turning the adjustment screw on the HPR clockwise. If your gun starts leaking, separate the front and rear halves of the body and inspect the o-rings in between for damage and replace if needed. Lube with Dow55.

      • Mainbody Front to Mainbody Rear: 1x18mm (Dura 70)

      • Manifold to Mainbody Front: 1x5mm x2 (Dura 70)

Solenoid:
  • Pressures: Could be that your marker is over pressurized. Using a pressure tester, verify your LPR is set to 65-75psi (Recommended is 70psi) and your HPR is somewhere between 165-185psi (Recommended is 180psi). Adjust if necessary.

  • Poppet: Before jumping directly into the noid, remove the poppet and inspect the cup seal portion for any nicks or damage that would cause it not to seal correctly. This will often times cause issues that make it appear to be an issue with your noid. If the cup seal is damaged, replace the poppet. Note: The cup seal is the white delrin piece on the front of the poppet shaft that looks like a plug.

  • Solenoid: Inspect the solenoid manifold and the connections on the outside of your solenoid and make sure everything is secure. If you find that the leak is comping from the solenoid, you have a few options. Take the brave route and attempt to disassemble and service the solenoid yourself, or, contact Bob Long Direct and make arrangements to send your gun to the super guru's at Blast and let them confirm and fix the problem for you. If you've never taken apart a solenoid and don't feel confident in your abilities to do so, this is not the brave route, it's suicide and you'd be better off contacting Blast. If you are comfortable servicing your solenoid, included below are links to step-by-step instructions (with pictures) on disassembling your solenoid. If you'd like to
