I don't KNOW the answer to your question, but my impression of the 150/250/255 lever actions, 270/275 pump actions, and 190/290 semi-automatics is that most of the parts are the same, only the specific parts, or differences, related to the operating system that are required to cycle the action are different. I'd bet that, except for the hole in the side of the bolt for the semi-automatic cocking handle, they will be interchangeable parts.
