Hi all. A little while ago I bought a Fx streamline which had very little use. These guns are very expensive which is why I am bringing this point to you. I have customised my pcp as that is what I do for a hobby. while working on the gun I, very disapointedly, came across some issues, the first was the pellet probe and the second was the air port adjuster wheel. They both leaked badly when taking a shot. I had to remidy this by machining my own custom pellet probe, slightly oversized and tapered so that it would squeeze on the breech seal tighter, also I included an aditional o-ring on the probe shaft, sitting just inside the breech, completely sealing the breech. I know that this is an issue with many pcp's as the pellet rides over the o-ring each time its loaded but this was losing a lot of air.
As for the port adjuster wheel, it too was losing a lot of air, both from the inner part and outer. I don't think there's an excuse for this one, its just bad quality control. The o-rings needed to fit slightly tighter when assembled, there was next to no resistance from the seals when installing the parts together and the air would easily escape when taking a shot. As I said this could have been prevented easily with just a little more care and attention. I resolved this issue also by finding better sized o-rings and deburring any holes for the o-rings to ride over easier. Problem sorted.
The main point here is that these problems should not be there on ANY pcp but especially such an expensive pcp. By the way just incase anyone was thinking if I tried just replacing the o-rings for new fx ones, I did and that made no difference as it was a matter of size and tolerances. I managed this work as I do a lot of this kind of thing but I know that many would not be able to or even have the tools to get the job done. As this is a manufacturing error there will be a lot of people out there with an expensive pcp that's leaking like a sieve and the performance drastically affected. I don't know about the dreamline but the early ones were very similar to my streamline and am sure they too have the same problems, maybe they realised the errors and corrected them - I don't know.
Anyway I thought I would bring this to attention. Happy airgunning.
