    Phantom shooting problem

    My phantom will only shoot about 5 shots before not letting any air into the valve. Each shot loses about 50 fps until I cock it and nothing happens. I’ve tried multiple 12 grams to be sure it wasn’t an air source issue. I’ve put new o rings on everything and it still happens

    What springs are in it?

    Are you 100% sure your internals are properly installed?

    Is it leaking down the barrel?

    Check that the cup seal and power tube are tight together.

      We sometimes play at a field near a freeway. We have a guy that will look across the picnic table we are standing around and say "you're leaking".

      Sometimes we have to hand the marker to him to find it.

    What's the ambient temperature?

      Is the valve spring missing?

        Take a look at this. Make sure #13 and #16 parts are tight together. If it still leaks flip #11 it’s the Cup Seal this should stop any leak. You could also replace it but flipping it will give you another decade of service. While you have it apart insure you have the stock Silver springs in your marker this will give you the best performance on 12g power. 2-2.5 turns in from flush on the TPC (down the barrel regular screw driver) should put you in the 300fps range.

          Try backing your velocity adjuster all the way out (even take it out and re-install, then re-chrono. Sometimes the spring gets caught and does some pretty unpredictable things.

            its likely the famous phantom heat problem. if it was hot 90-100°, and your Co2 is hot the pressure spike from the expanded Co2 can put to much pressure on the valve spring dropping your velocity off. super frustrating, and not unique to all phantoms - some do and some don't. play around with different valve springs and see if you can find one that works. I have 2 phantoms that are fine and one that just refuses to work.

              Temperature has been around 80-90 degrees when testing it out. I just flipped the cup seal and putting it back together now. I only have the red spring, not the silver but will try a silver as a rebuild kit is on the way. I’ll try HPA instead of CO2 just to see if it is due to the ambient temperature

                Big thanks to everyone for the advice. I’m new to the phantom world and y’all have been more than helpful

                  It’s almost as if the valve thinks the co2 cartridge is empty. I rebuilt everything (still waiting on the silver spring) and now I can get around 10 shots before it drops off. I kept the co2 inside over night but after 8-10 shots it just acts like it’s out of air. I’m about to try taking the valve spring out and reinstalling that now.

                    Is the sear not catching? When you vent the 12g is is still full?

                      its the red spring causing the problem. need the standard silver for c02. Red is heavy, blue is light. Silver is just right.

                        Yeah the 12g is very full once I vent it. I shot a few hundred rounds through it with the red spring. It was only when I added the set screw to the grip frame to block the airflow did all of this start happening. I’ve since took the set screw out but it will randomly start leaking from the airline in the grip as well as just stops shooting and cocking after 5-10 shots

                          Oh it’s a 2.0 frame. That makes a difference, check that the valve and all of the Sealing disks are properly aligned. If it’s off set a lil it may be blocking the flow of pressure. If it’s not tight it will leak.

                          I had to switch to a red main Spring with the 2.0 frame it’s likely your issue as well.

                            I currently have a red main spring installed and I’ve disassembled and reassembled a dozen times. I’ll try it again but hopefully the rebuild kit helps

                              It must not be getting pressure. I would check that there isn’t something blocking pressure to the valve.

                              If you install the stock parts dose it work fine? Or you only have the 2.O frame?
