I don't know if you're open to importing a stock, but my friend Robert Flerin in Slovenia makesfine stocks for the Baikal Artemida. Robert also makes stocks for several of the Ferlach gunmakers, and does not need my praise, though, of course, I am always happy to plug for a friend. He uses thin shelled Slovenian or Austrian walnut for his stocks, and you can contact him on Facebook. You won't find a nicer guy to talk to, whether you choose to buy from him, or not.

I have read of someone who makes a rib for the Artemida, to fill out the gap between the barrels as well, but can't remember where I read about it. When I remember, I shall post the details here.

Also, as several of the members have said, you might find it easier to buy an off the shelf double rifle from one of the many names in the business for less than the price of a customized Baikal. Best wishes with whatever you decide to do, and good hunting!
