Are diameters of PX100 short and long barrel variants same?

[Kharsang]

I am planning to replace the barrel of my Precihole PX100(short barrel variant) with a new one. I was wondering if the diameters of short and long barrel variants are the same? Are the barrels interchangeable? Will it be possible to replace the existing short barrel with longer ones? Thank you.

Where do you get those long barrel

[Kharsang]

PX100 with long (Club Pro with 580 mm barrel) and short barrel (Achilles with 500 mm barrel) versions are available online. I not sure though if the barrels are sold separately. Maybe the esteemed members of this forum could help us with this doubt?

Why do you want to replace the barrel?Is it to increase the weight of your airrifle?

[Kharsang]

As a rule of thumb, compressed air guns gain velocity with the barrel length.The expanding gas has more time to push on the pellet in a longer barrel. And therefore, the air required to push the pellet is significantly lesser in longer barrel (Hammer spring has to be adjusted accordingly) and thus more shots per fill.
All these information were collected from various gun forums on internet, and therefore I want to try and modify my PX100.

Yes, it's a known fact.But are you sure,the barrel is 80 mm longer than Achilles.It is possible that it's the muzzle weight on club pro that's adding to it's extra length.If you need more shots per fill, install a high capacity cylinder or carbon fiber bottle.

Barrels are not sold separately.

These are the specification of both the variants:

That's a shame!
Any idea of where pre-owned (used) air rifles are sold? If not sold separately, I suppose, no other option but to source it from a second-hand market.
