Remington now imports the Baikal shotguns under their 'Spartan' brand. Barrels for the "Remington" Spartan SPR-453 are the same as your Baikal.
Canada told me that Baikal does not send parts and Remington no longer sells the Spartin or Baikal They will referr you to EAA corp

Baikal shotguns have been around in the UK for a long time now. They are very simple and honest hardworking guns that will give many years of service. I own two Baikal shotguns (both singles) and I often choose them intead of my Beretta 391 semiauto. Prices in the UK for new baikal guns are about: single all guages L89 side by side L260 over/under L340 You can go to Baikal's website at www.baikalinc.ru. Be sure to click English version when the page pops up unless you can read Russian! Has lots of information and you can even contact the company via email.
Baikal parts are available thru EAA Corp. Below is a link to their parts store. http://www.eaacorp.com/manuals-parts-diagrams.html
probably not, historicly shotguns are smoothbore if you shoot a slug, THAT would be rifled.
IZ shotguns, also the Baikal brand use the TruChoke system sold also by Colonial Arms. This is the same choke style used by the Remington Spartan line while Remington owned the rights to the Baikal design.
There is a main dealer in UK and have loads of parts, old and new.
