    Hey guys,

    I've encountered an issue with my new Mk2 which I had about two weeks. Here is a video of the issue:

     

     

     

    After the trigger is pulled, the gun won't fire, but the hammer spring can be heard moving. Air can be heard moving through the front area of the gun (barrel or gas tank? idk). Immediately after the shot, as I uncock, there is a hissing noise and air/steam that releases from the butt of the gun. As far as I know, no mods were performed on the gun, so I am not sure what is causing this issue. 

    The regulator is currently at 98ish (slightly below 100). The wheel is set at Max. I have not modded or tweaked any parts of this gun. I have only used factory settings.

    When I initially got the gun, the current issue occurred, but I believe that was caused by shrapnel (probably caused by two pellets loaded in the barrel and firing at once) in the barrel which prevented the gun from firing properly. I took out the barrel and removed the shrapnel and it solved the problem. Between that initial issue and this current issue, the gun fired off 100+ shots perfectly fine. 

    Does anyone have any idea what the problem is? I would greatly appreciate your help.

    I would Take the magazine out dry fire couple times if you double loaded (or triple or quadruple loaded) try shoot normally if still no go take the barrel liner out and check for pellet obstruction run a wooden dowel through to clear it if that's the case.

    Before doing anything! Unscrew that LDC first!

    If your reg pressure is good sounds like you have may pellets stuck in the barrel again.   Or pieces stuck in the barrel/valve port.  Pull the barrel again and then turn the gun upside down and shake it.  Look inside the breech block and the barrel ports for obstructions.  If there are none check that the hammer seat is still in place and adjusted correctly.

    After all is well again try to take out the magazine out actuate the cocking lever partially toward and see if the pellet pusher probe wiggles that might be loose.

    When there are questionable problems always remove the magazine to avoid double loading and unscrew the LDC so it doesn't get damaged shooting multiple pellets like a shotgun. Dry fire to clear and when you hear a loud bang it's shooting normal.

    Sounds like the barrel port has been altered to me.  Does it have the stock probe or one of the newish pin probes?  What caliber and ammo are you using?

    I tried dry firing but still won't shoot normally. There is still a hissing noise/air release from the back of the gun after I fire and then cock the gun. I also pulled off the barrel shroud and LDC, and then I shook the gun while it was upside down to see if any pellets would come out. There was no noise of loose pieces inside the gun.

    Now on the hunt for a wooden dowel…hmm…

    I am using a .25 cal with JSBs 25.39. The barrel probe is stock. I am not sure if I would void the warranty for trying to look into the breech block and the barrel ports?

    Also, you mentioned the regulator. The reg came out of the box at around 98ish. Would that be a cause for concern?

    Here is a video of the "hissing" noise when I cock the gun after firing. You can also hear the strange air noise going through the front of the gun.

    That noise is normal.  It's the PP refilling.  The hammer is not opening the valve it sounds like to  me.  Set the power wheel on max and with a 1.5mm hex wrench, turn the hammer spring adjuster clockwise for more power to open the valve.  I'm thinking possibly your adjuster has backed out on you while shooting it for two weeks.

    This is what I'm afraid of with the huge wait and so many pre-orders for FX guns over the last 14-20 months.  The dealers already have the customers money and FX already has dealers money before a gun is even made.  Some have theorized that FX quality and quality control has suffered.  I truly feel for you.  A gun that cost this much that you probably waited months for already, only to possibly have to send it in to have work done on it and wait several more weeks to get it back.  All for a 2k+ gun is absurd….

    No concern with the 98ish on the reg.  The probe is a standard one.  It will not void your warranty to pull your barrel and take a flashlight and look down the barrel opening in the breech block to see if the valve transfer port is plugged by a pellet or piece of one.  If you find nothing there and the hammer seat adjustment is goodI believe the hammer seat should stick out about 6.5mm give or take a little, triggertreat has some good info for you also

    Take the barrel liner Out and see if there are stuck pellets inside so if you can't see through any light and use a wooden or fiberglass (NON METAL) rod to unblock it.

    Removing the barrel liner should be the FIRST THING TO CHECK for obstruction.

    Shaking the barrel/gun won’t get ANY pellets out, aim the barrel out to a light, you should be able to see thru it to the light, of you can’t, you have a pellet or pellets STUCK in that barrel, like others have said, use a wooden dowel to get them out! It is a PIA but can be done.

    Not talking about the barrel it should be out and checked first.  Talking about the gun sometimes pellets/slugs or pieces of them get rammed down the port.  Just had it happen yesterday and turned the gun upside down and shook it the slug or the better part of one anyway fell right out.

    Sounds like double, triple load etc.  Remove the 3mm set screw and take the barrel off.  Do you see light through it or no?
