Tuning Any recomendations for getting an older brocock re-finished and re-sealed?

This one exceeds my current access to tools. I can't get the airtube apart; not without damaging it. And the barrel seems to be pressed into the receiver?

In any case, I want the bluing re-done on just the tube and barrel. And a basic re-seal.

Any leads?

Gun is a 2017? grand prix pistol.

I think the best thing you could do is to just sell the gun to me.

Haha. Well, if I ever do sell, I'll let you know.

I am under the impression that Airguns of Arizona is the Brocock service center. They said they service them when I bought a used one from them.

I'll reach out to them and see what they say. Thanks!
