FX Pellet probe is kinda stuck in something

[Gambler]

Hi. When I was shooting my drs today i noticed that my barrel had moved 1-2mm forward (the brass that sticks out to guide magazine was flush with the block) dont know how long its been like this, probably since I upgraded it from 177 to 25. So I let all the air out today and took off the air cylinder loosend the 3 set screws and pushed it in and put everything together and filled it up again.
But now I had to force the cockinglever open the first part, I tried to close it and it goes smooth all the was until the last mm. This was not a problem before when the whole barrel assembly was "wrongly" mounted. Does the liner go all the way back so my pellet probe get stuck inside the liner?

Edit: there are no visible marks on the probe.

Is there a pellet in the barrel you might have forgotten about?

 

[Gambler]

Nah, I can put in a mag and shoot normalt, except for the hard "final stage" og the lever

Did you clean the barrel while it was out? You may have some grime built up in the mm that wasn't being used to seat the pellets when the barrel wasn't all the way in.
surprised you didn't have accuracy issues and I'd guess your speed was different.

 

[rc4fun]

Or more likely you were not used to the force required to get the pellets fully seated past the breach O-ring.

 

[Gambler]

I did not clean anything, just loosend the 3 grup screws and pushed the barrel assembly in all the way where it supposed to be. I did not have any acc or fps issues before either, but after pushing it in where is should be i gaind 20fps so maybe the 2 transferports where not lined up before. But still dosent explain why the probe gets stuck, I can try to film when I come home from work.

 

[Gambler]

Dont know if the vid makes justice enough for how hard it is

Anyway a pellet can get behind the probe or under it. It looks like its coming open hard also.

Yeah it looks like maybe an oring or pellet chunk is in the path of the probe, or your probe got bent some how.

 

[Gambler]

I dont think anything is stuck cuz I can put in a slug and push it in with a ziptie the same depth as the probe should do.

It shoots like a dream tho, but the hard reloading makes it less smooth.

 

[DeanB]

Is it hard to cocking pulling back like it looks in video if so that indicates something is putting it in a bind. I had same thing happen to a Avenger and it ended up having a pellet somehow getting into the cocking linkage and was smashed in it making it hard or rough to pull back and push forward.

 

[SilentSquirrel]

Perhaps the probe is slightly bent, or the mechanics of moving it are misaligned
Look carefully at it from as many angles as possible.

I do not know the DRS.
Can the probe be removed easily for inspection?

[Gambler]

Its normal to cock after I get over the "bump".

And it was not like this before I moved the barrel assembley where it supposed to stay. I didnt even put a slug in it.

 

[DeanB]

I cant see where pushing the barrel up to seat it would effect the probe unless you didnt cock the gun 1st and maybe it hit the probe as you pushed it forward and maybe bent probe as SilentSquirrel stated. Something has to be stuck/rubbing somewhere or probe is bent out of alignment.

 

[Gambler]

Ill take it all apart tomorrow and see what I can find

 

[Gambler]

The probe hits the liner is whats the problem, I dont know if there is any adjustments to the probe so I can dial it back 2mm? Cuz the liner will have to stay where it is, and option is to put on a slug probe so the edges on the probe wont hit the liner ? Also looks like the probe pushes too far when lining up with the tp so the best would have been to adjust the probe back if thats possible?

 

[humbled.ag]

If there is no adjustment in the linkage, I would suggest using a honing stone and bit by bit removing material from the front of the probe until you have the clearance you need. That, or open the lead in your barrel enough to stop the binding.

 

[Gambler]

Yeah i was thinking of take abit off from the probe, i also tought about opening up the liner abit but was unsure of how it will seal agains the slug/pellet. So a quick fix now was Just to take the liner out and put a oring in the to get the needed space for the probe, dont have any idea if it will blow out, if it does my liner will become loose xD but I put everything back together and shot 20shots im happy with without getting the probe stuck. Theese are easy airguns to take apart, the longest time is to drain the air out

 

[elh0102]

That seems like either a machining error or a basic design issue. I would find a washer of the correct dimension (not an O ring) and let the barrel headspace on it rather than the liner shoulder.

 

[Gambler]

Yeah, if the o ring fails i just take it out and buy a slug probe, its on the shopping list together with a 700mm air cylinder anyway. Just hope it works now a little bit first
