If you are OK just shooting at the range, take a look at the S&W, or Colt models, or a rimfire upper on the real thing. Restricted, so you need an RPAL, and a range membership to shoot it.
Wasn't at all impressed by the general build of the Mossberg. I would save my money for about anything else.
That pretty much leaves the 597VTR, and the SR22, for off the shelf picks.
Guys say the Remingtons shoot more accurately, some have had issues with the extractors. Rugers have the aftermarket parts availability pretty much tied up.
Or you can start with any Ruger or clone, and spend from there, whether it is as simple as a rattle-can of flat black paint, or a full-on dress-up in AR parts.
Your choice.
