Got a cva kodiak magnum in need of some tlc. Gotta buy a breech plug, clean it real good, find some sights or a scope, find a recoil pad, and bolts to mount stock to gun. For the bolts im gonna take it to work with me and get some stainless bolts. As far as cleaning, somekne said to use dawn dishsoap? The barrel does have some rust spots on the outside, but not major. Just some light rust and pitting. I may clean it up and paint it or who knows. Whats the best way to clean the inside of the barrel? Does dawn actually work?
