Fx impact MK2

As far as cleaning the regulator, did you re-apply silicon grease to the piston ,and o-rings and curved washers? The grease helps parts move consistently as needed. If the regulator pressure isn't settling in the same spot every time it will throw off the es.

Why have you not contacted FX? Since you are in Denmark, it seems that contacting FX direct would be appropriate. If it needs to be returned, I would think the shipping time would be short. Aren't you about 500 km from FX? There is no need spending so much time and energy trying to get a new rifle to shoot. FX will probably claim you have voided the warranty if you install the Huma reg. 

I hope the Huma reg helps, but I'm afraid it is not the problem, or not all the problem. Assuming no issue with the hammer and spring assembly, I would suspect something in the barrel assembly. You should probably be sure that you are not going to seek further assistance from FX before installing the Huma, as I expect they will claim it voids the warranty. 

FX is very innovative, and they make some interesting products, but the new stuff is too complicated for my taste. And the way they continue to design and re-design things at a frenetic pace, it suggests to me, maybe they aren't spending enough time in perfecting fewer, but very solid rifles. I don't need one rifle to do everything, it just needs to do a few things very well, and in a reliable manner. The only FX rifle I currently own is the old school Royale 400, IMO the best rifle they ever made, and one of the best I have ever owned. But I digress, good luck in resolving your problems. 

Yes, I fully understand your position regarding the dealer. But, if FX accepts the return, then the dealer is out of it.

I know the OP is not in the USA but for people in the USA installing a Huma regulator can not void the warranty under federal trade laws. Falls under this same rule https://www.ftc.gov/news-events/press-releases/2018/04/ftc-staff-warns-companies-it-illegal-condition-warranty-coverage

This is a very slippery slope, and one with which I have had some experience. True, the FTC reg attempts to offer protection to consumers who choose to use other maker's parts. But in practice, it often becomes a matter of how the maker claims the part in question may have been detrimental in some way. The argument may be without merit, but the time and cost of challenging it can put the consumer in a difficult position.

Depends on the size of the company and in this case it would be impossible to prove the Huma regulator does any harm. It would be foolish for the manufacturer to let this go to court.

Not a matter of going to court, that would never happen (unless it was a much larger monetary issue). The problem is dealing with one person after another until someone finally authorizes the work. Meanwhile, you have rifle that you can't shoot, or a car you can't drive, etc. You are totally right, it would be a dumb decision, but it happens. Sorry, didn't mean to get off topic. To the OP, sounds like you have a plan, good luck. 

Much better!

Good job, I don't understand why FX wants to keep using the plastic piston. Sometimes good enough just isn't good enough.

spyde82, that has been an ordeal you just went through with that FX MKII. I am glad that you have found the solution to the issue and hope that you are smooth sailing from here on.
