I'm needing a bolt assembly for a Derya MK10 12g. I can't find parts anywhere. I've checked gunpartscorp with no luck. A few gunsmith have told me repairing the bolt isn't possible. Someone might be able to fab the part but at what price? Ive been told that a lot of the Turk parts are interchangeable but no one can tell me what crosses over from one gun to the other. My little girl won the shotgun and I'd really like her to have it one day. Anyone have any tips?
