I have a marlin 30AS that the front and rear sights are drifted quite a ways to the right. My dad bought it for me as a first deer rifle, and it came packaged from the factory with a scope. I wonder if this is why, because with the irons drifted this far I don't think it would otherwise have sold. What causes a barrel to be off like this? Could cutting and re-crowning fix? I am looking for a marlin to cut down to 16" for a iron sighted brush gun, would this be a good candidate?
