Guys looking to buy a new semi auto 22 long rifle stainless what's the top 3 semi auto loaders on the market?

10-22 always ranks well. Browning ATD for looks.

IF you are after current manufacture semi volquartsen is hard to beat though certainly not inexpensive..

10-22 although it's not always the most accurate off the shelf.

CZ 512 though it isn't stainless.

Put a Tactical Solutions barrel on it.

Malin model 60

Vote Ruger 10-22 also... I've got a couple the kids have a couple, if you are into it you can upgrade the trigger yourself with a couple of stones and about $10 in springs from Brownell's. They are fun to work on!

Though Tactical Solutions is a step up from the average factory barrel for near the same money I would go with a Beyer, Kidd, or Fedderson Barrel on it, or for the least amount of money you could have 'Que' over at rimfirecentral set the factory barrel back & rechamber and crown it. Depends on what you are looking for.
