No. The stocks are not interchangeable. Boyds make some nice aftermarket stocks for the Remington 597 as well as the Ruger 10/22. The Ruger 10/22 has all sorts of aftermarket parts to customize the look and performance of your 10/22. The Remington 597 is just now beginning to get more aftermarket products available to customize your rifle.

Well the mini 14 comes in stainless steel. That is made by Ruger. There is also a Ruger 22 cal. stainless steel rifle.

Yes, marlin has now release their thumbhole stocks for models vst and vt to the public. Price is $99, but you have to call them. Their website isn't even updated enough to show the new models, let alone the stocks. The number is listed on the website however. Also, Revival gunstocks has been rumored to sell their tundra for the Marlin, but I haven't been able to confirm this since their phone lines were down when I called them. They list only Ruger 10/22 stocks on their website. This answer is assuming you are talking about the Marlin 917.
Marlin and Ruger are two.
