Is my thinking Wrong?

All modern pcp rifles are ready to shoot out of the box.

What the companies are not able to know (and this includes also the high end makers) are the personal preferences of each one of their clients.

The guns are tuned so to satisfy the majority of the buyers, the rest will tune/tinker/custom/adjust according their needs or the very personal definition of "best gun"

When I bought my Impact X from Utah Airguns it shot JSB 18.13's at 870 fps. The reg was just over 100 BAR. After a while, I turned the reg screw about a 1/8th of a turn counterclockwise and the reg went to just under 110. I now had a MAX speed of 910 fps. (On MIN and 1 the speed was IIRC, around 750 fps) 

It shot perfect and after 12,000 rounds it rather suddenly started to loose velocity. I sent it in to FX where they replaced the C3 bumper. It leaked when I got it back, so in it went again. They replaced some Rings and it is running like a champ. (Thanks FX) 

So in spite of all the doom and gloom stories, I can not say enough about my "high end PCP".

I have waisted lots of money on guns in my younger days. So now I don’t rush to buy. In my opinion since “we airgunners” tinker with the guns the manufactures get away with putting out unacceptable guns. Read how many new guns go back. Posts complaining about quality have kept me from buying. I realize each gun was designed with a pellet weight, velocity and energy in mind. If a guy wants something different the maker can’t be held accountable. Coming from firearms we can adjust powder primers. To adjust speed power. And here the energy is the heart of the gun. I do wish the "Airgun industry” was held to higher standards.

Maybe the OP is referring to spending the big bucks on a PCP at least hoping for a problem free experience for years or at least until the expected time the orings need replacing.

I must be extremely unlucky because I spent $1400 on a new Cricket that leaked within 200 pellets so it had to go back and had other little nitpicky things I didn't like about it so I sold it at a $300 loss within 3 months. $1600 on a new FX Revolution that spent more time at the shop than when it worked so I actually demanded a refund on most of my money after the 3rd time it broke within a year and it was also stupid how the trigger design pushed back on my finger when pressed. $1900 on a new FX Impact that had an aggravating amount of problems all going on at the same time, I sent it back once under warranty and the reg failed again within a few weeks, it was a lot of work for my friend to diagnose the various problems and sort them out. So you don't think I hate FX I do have a FX Royale that has been a great gun.

These don't include the other PCP's I've had that had little things on them fail, or that had POI shifts, etc.

Okay maybe if I bought a $300 PCP I'd except some minor annoyances but it should work right out of the box, Yuh know for $$$$ that expensive gun should be GTG from the onset and pleasing in almost every way including being reliable for years to come. 

BTW for the most part I only adjust the trigger on my PCP's and I leave the technical stuff to Smiths. I learned years ago that I have the ability to tune things to a stand still so I don't mess with things I don't understand.

Honestly anymore, I'm actually a little fearful when I buy a PCP! 

IMHO your thinking is not wrong IF you get an FX Royale or Boss! High end gun, no tinkering, just fill with air, load & shoot. Simplest platform made by FX. Perfect for guys who just want accuracy, reliability, SIMPLICITY!!!

I think the issue is the relative complex nature of a PCP rifle as compared to let’s say a 22 rim fire. The nature of the critter. I’ve had and have Daystate Brocock Cricket RAW and FX guns and I can say I haven’t had any problems with any of them. The RAW as per its reputation seems to be the most trustworthy of all of them. The Daystate is just elegant . The Cricket probably as good as any of them accept for the trigger. The Brocock worked well I just wasn’t satisfied that it did any thing special . The impact is a work in progress. If you don’t need high power and long range I think there are better guns out there for less money. Some of them FX. It remains to be seen if I can spend my way into an impact that will light my fire. I’m not especially enamored of the bull pup configuration. I do like the fact that the gun can be tuned for a particular type of shooting. I would just caution every one that there is no perfect PCP and none of them are head and shoulders superior to others. Much like 22 rim fires a n anschutz 54 is not that much better then a 64 or a Cz Nice to have but hard to justify if you need to justify.

Short of it PCP’s are going to more then likely require fixin. If that is a deal breaker buy a good springer.

Some of the PCP’s will probably hold up better then others which one’s ??? I’d say that for the most part no one knows. Maybe the guys that service them. Talk to the guys at Baker air guns get their opinion before you buy . I’d think their opinion worth more then what you read here. Not that our opinions are useless just not as much as the experts 

While PCP air guns are relatively new. High Pressure pneumatics are not new at all a pilot valve that can direct high pressure air has been in the industry for decades. If the pistons fit cylinder, and the o-rings are quality fitting in good races the valves can last for years. We did our maintenance on a 5 year frequency on equipment that was out doors. So the engineering ability is available. Manufactures could make quality dependable valving. At work we use 4 stage compressors from the 70’s. But could we afford it?
