FX My FX rifles good news and bad news

In my pcp collection that includes FX, Air Arms, Daystate, RAW, Kalibrgun, Weihrauch, and Brocock air rifles, my FX air rifles are among the smoothest, most accurate, most ergonomic, and powerful. They are an absolute joy to shoot and I have no regrets.

The bad news, they require absolutely the most maintenance. Within the last year, I have purchased a .22 Panthera 700mm, a .22 Impact MK3 600mm, and a .25 King.

The old .25 FX Royale in my collection is superbly accurate and has only been resealed once in all of the years of service.

The Panthera was back to FX 3 times within the first three months of ownership before they were successful in stopping the leak off situation that occurred between shooting sessions.

Me new King and Impact are virtually new and both are now leaking off. I have not developed the knack of successfully finding the leaks, and they are still under warranty, so they will both probably be going back to the very reputable dealers for repair in the coming weeks.

None of the other rifles in my collection show the propensity for so many leak issues, but I enjoy the FX rifles so much that I tolerate this, and have just come to accept it and expect it as part of owning them.

This is not a complaint post, just letting those contemplating such purchases to be prepared to have some patience.

Great post I highly respect your opinion through useage of the different brands. That said, the shipping back and forth with the FXs’? I personally would not have the patience to deal with that. At the prices these guns command? Zero issues should be the norm. You have the luxury of using your other fine PCPs while your FXs’ are being “worked on”. That could be a big reason for your tolerance of repeatedly leaking FXs’?
 
I thought some day FX would make a simple Impact,From the very beginning FX has said the Impact is the most complex air gun made and its not for beginners its for advanced airgunners,, EXAMPLE, people said the RTI was a copy of the Impact,But the RTI gun is simple and it has very few 0 rings , The FX is packed with 0 rings , Sorry I do not have the numbers for the guns. Why does FX need so many 0 rings to make a Impact,,,
I always say , Keep it simple.

Nice post. When I can't find a leak I dunk it.

Sorry to hear about the leaks!

Don't understand that - I have 4 FX PCPs (Royale 500, Crown MK2, Impact MK2 and the Panthera) and over the years (and thousands of pellets/slugs) they never needed any more maintenance than cleaning the barrel, a bit of lubricant and checking the screws were still tight.

Hope you get it all fixed up!

Cheers!

The same here
4 year old Impact mk2 never leaked.
Also had 2 Streamlines and 2 Royales and neither had a leak or any sort of problems.
I also have Dreamline classic and again no problems.

I am going to sell my Kalibrgun cricket II tactical .60 thats has been working flawlessly to buy the new FX King with his beautiful GRS stock. But after reading this, now I am not sure if this would be a wise decision taking in consideration that I don’t live in the states and if I need any kind of services durring his warranty period It will be very expensive to me to shipped back to the states to do the repairs.

Do you consider this FX King backyard friendly? I am not sure to buy it in .22 or .25 cal, I already have plenty of pellets in both sizes because I have three more airguns. Any reason why you choose the .25 over the .22 cal? Thanks

Nice post. When I can't find a leak I dunk it.
ok.. I just thought PCP and water and moisture was not a good combination.. but it is how I check tires and when I did excavation we always did a pressure test overnight on gas and water lines.. but we used soapy water to see the bubbles easily..
I have a american tactical liberty nova 22 that I got around 8 years ago.. I believe they are not in business anymore and it's started to leak down.. it drops 1000 psi per week and stops at 2000 PSI and that I think seems like the regulator pressure setting and has held that for a month now..
does anyone have a idea where the leak might be.. it very similar to the avenger and regulated but it is adjustable but no regulator pressure gauge..
I'm thinking if it was tank it would go empty.. same with the valve.. so the only place I can think of is the regulator atmosphere vent area..
any ideas??

I have a Donny Fl Sumo moderator on my King and shoot it in a fairly urban setting in relatively close proximy to my neighbors. It is sufficiently quiet.

Yes, check the weep hole for the leak when the bottle pressure is above the reg set point. If that's it, then you just need to replace the external O rings on the regulator.

I've read somewhere you can use silicon oil to find the leaks, I'd bet on regulator. I know that on the Maverick they changed some of the internal o-rings from 70 to 90's but it's not reflected n the prints. The two little ones on the adjustor are now NBR 90's and are a PAIN to get on, or more of a pain. The only way I've found is to chuck them in boiling water to soften them a bit to get them to stretch. Mine have been perfect on my two Mavericks. I'm going to assume that the regulars are the same, could be wrong but....incase they are... FX hasn't posted a schematic for the King so I can't check it. The Impact M3 is showing the NBR 90 O-rings

I've been digging deeper into the FX Mavericks o-rings and I've found that there are serious errors in both the online schematic AND the schematic they send with o-ring orders.

The schematic sent has different hardness's i.e. NBR90 instead of NBR70, this makes sense except one is several mm thicker than possible in it's location. The on-line schematic has the old durometer numbers but the right sizes. Numbers below correspond to the online schematic.

13) 10.0 x 1.5 NBR90 inside Regulator hole at bottom of threads

18) 7.5 x 2 NBR70 Regulator Body

20) 4.0 x 1.5 NBR90 End of Piston

23) 4.0 x 1.5 NBR90 Inside Regulator Body

25) 2.0 x 1.0 NBR90 (2x) Adjustment Screw, suggestion heat in boiling water slip on first one, then second one, or if you have a witches hat it’s easier.

I should specify, I am comfortable taking mine completely apart too and I dry every thing after. If it doesn't require a complete tear down, a regular air compressor works to blow off water. It also depends on where the leak is. I may not even have to dunk the whole gun.

I couldn't find 4x1.5mm O ring in 90 shore in any drawings of FX guns regulators.
