Hello everyone, I have an fx crown mk2 0.25, and after a few days of use a pellet got stuck, I removed it but sometimes between 10 shots it got stuck again, I have 145 bar with 23 on the hammer, I also noticed that the shots are not grouping well, since the fx is almost perfect in this regard, can someone help me? Thanks
FX Fx crown mk2 pellet stuck

Is this a new gun to you? If it is not, did you make a change in pellets you are shooting? When you say not grouping well, can you be more specific ?

Which xfer port are you using?
° if it's the slug port, you could have a piece of pellet stuck or even got a piece that dropped into the xfer port. I'd pull the barrel and inspect.
° also, check the barrel o ring, you could have damaged it while pushing the pellet out.

Your liner may have a burr or leading if it can squib a pellet with minimal bore bearing surface. First steps I might take is use some yellow lead cleaning cloth from a gun store and clean the liner carefully avoiding multi piece steel rods. I use coated carbon rods on all my barrels, air or powder after marring a bore.
Secondarily the gun should have the power to overcome this debris st 145 bar and be inaccurate while it does it. I would take a look at all your orings from the valve to the muzzle and make sure they're fresh and sealing well. If it continues, i might just buy a new liner.
In the future wash and lube your pellets or shoot silicone lubed cleaning pellets every so often to help non-stick your bore perhaps? There's other ways to dope your ammo but I can't speak to those in fx liners. Like moly coating or hex boron treatments etc.
Hope this is any sort of help. Good luck.

No problem, if you discover the cause of the failure I hope you update us here. I'm happy to try and help.

I'm thinking about returning it, it's only been used for 10 days and since it's an FX worth $1800, I shouldn't do that.

Run a patch worm and examine the patch and look for shredding or lead plating flakes. Maybe that might tell you something.

Right off the bat the tune seems too hot for shooting pellets. Too much reg pressure and too much hammer mess a very log air burst that is probably washing the back of the pellet after it leaves the barrel. That is a likely cause of the poor accuracy.
As for the pellets sticking, do as others have suggested and pull the barrel and make sure you have nothing with the ports that would cause a pellet to jam.
Best of luck

Getting pellets stuck seems to go with PCP ownership, especially FX. I've learned to carefully and smoothly cycle sidelever on M3 and Wildcat to avoid. Recommend all PCP owners secure a wooden dowel, or coated pushrod, of correct diameter, to clear jams. Wood, or coated (plastic/fiberglass,) rods are essential to avoid damaging the muzzle crown (beveled internal edge.) Bad, or damaged, crown allows uneven air flow to destabilize pellet on exit, leading to poor accuracy. WM

I agree that your set-up is too hot and not economical
Lower reg presure ,about 110 bar , lower hamerspring tension , i guess you're waisting a lot off air
remove the barrel if you Got a stuck pellet ,so you can push it out away from the breach

Any gun could, and often something is overlooked by the end user or a variable isn't being stated about a particular hiccup.
If you have the warranty use it, but understand that the fx guns are good parts in a box and it's up to us to make it what we want thru tuning. Imho.

HI,
My two cents on this. I am assuming you have the superlight barrel system on the Crown MkII. That is a unique system where the barrel liner is held in the barrel cone (part 7 below) by 5 o-rings that are squeezed by the Liner Nut (11) being screwed into the Cone. The liner must go all the way through the Cone, through the Barrel Attachment (part 4) and seats in the Barrel Inlet (part 2).
I had a case where I double loaded my Crown and tried to fire the pellet out. When that didn't work I took the barrel off and uses a cleaning rod to get them out. What I failed to notice was that when I tried to fire the pellet out I actually pushed the barrel line about 3 mm out so that there was a gap in the barrel inlet (part 2) between the end of the liner and where it was supposed to seat. The result was that over the next several shots I got another jam. This time the pellet dropped into the gap when being loaded and it was crushed by me pushing hard of the loading lever. This one was tough to clean out.
So, you might want to take off the Liner nut and pull the liner to see if everthing is clear. Then make sure the liner is fully seated all the way into the Barrel Inlet before tightening the Liner Screw on the o-rings.
Cheers,
Greg
