That is a VERY broad question.
You can get integral or a screw-on muzzle can.
You can get sealed, or a can you can disassemble.
You can get aluminum or stainless steel.
Some .22 suppressors cost over twice as much as others.
Narrow down what you are thinking about and we can go from there.
I am considering the SWR Spectre myself.
I have several others also.
