Remington now imports the Baikal shotguns under their 'Spartan' brand. Barrels for the "Remington" Spartan SPR-453 are the same as your Baikal.

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 isn't made buy Remington; it just has the name stamped on the side. It is made by baikal of russia
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.
Parts for these shotguns are hard to find. EAA Corp carries parts for Baikal shotguns. A good gunsmith might also be able to help make some parts.
Yes
