Educate me about the Mossberg 146b. Quality, accuracy, value? The one I am looking at has the factory peep sight on it. Looks to be in good condition. Trigger seems a little stiff for a target rifle. Can it be improved? It belonged to a gentleman at the ranges father. He has no sentimental attachment to it. I don't need it, but I do not own a bolt action 22 and thought this might make a nice 100yd gun. I have no prior knowledge of them so any info would be helpful.
