While I know that this rifle uses a lot of Zamac in the receiver, it is kind of appealing nonetheless with the classic styling, walnut stocks, octagon barrel, and Marbles sights. Can any owners give me their impressions of this rifle? For instance, I seem to recall reading somewhere that the action was a little stiff. Is this true? How well has yours held up to use? Any undue parts wear or breakage? Reliability issues?
