Need some info and advice

[beag_nut]

I have a Crosman 600 CO2 pistol, which I have owned for 60 years (!). After replacing the main seal recently, it shoots like new, which is phenomenal for a CO2 handgun. Now, though, I want an air rifle. I don't want PCP if I can avoid it, but I don't know enough about the offerings available in air-piston rifles yet. I looked online at the Hatsan offerings and they look promising, but I don't like that the #155 (for example) has a barrel that is not fixed to the receiver. My question is: what is out there which has a fixed barrel and no moving spring (while firing) in .22 cal.?

Thanks in advance

The Benjamin 392 multi pump rifle is an option. .22 cal, fixed barrel. Bolt action.
