I think whats confusing you is hte same thing that is confusing me. I bought the gun new in 2002. Had the pre 64 tags on it with the claw, im sure you know what im talking about. I think, this refering to the extractor used on the bolt, being the same type used on the model 70's manufactured before 1964. But I am unsure what aftermarket stock I would need to purchase if I decide to go syntheic. Not so much as the brand of stock to order, but rather the action to order the stock for.
