with the breach block ( and all that comes with it) so I can just take my barrel assembly off and put the new one on
I believe the Hw 90 barrel assembly is the same as the RX2
you would have to verify that with the order, especially the cocking arm.
TW chambers sells the individual parts,
What caliber? PA has .177 (only 1 in stock) & .20 (2 in stock) barrels.

As for getting one as a complete assembly, I don't think they sell them that way. So you'll probably have to use your cocking lever with the new barrel. And I'm not sure but, you may have to swap your lockup components over to the new barrel as well.
