I purchased a Baikal coach gun a few weeks ago; it is a KH model, but it comes with a Baikal recoil pad and does not have as much trim on the action, so I am assuming it is an older version. I like the little bugger, but I would like to have it modified for choke tubes. The Baikal website states that the new KH models have chrome lined bores, which i have read are a b**ch to have modified for choke tubes. Does anyone here have a way to determine if the bores are chrome lined or not?
