I just received the extractor and a hand guard band with a sling swivel. Also won a bolt on auction. A few problems so far. One. I have no ideas how to remove the pin for the extractor (my rifle has the pin installed with no extractor).  Also, the screw for the hand guard band does not fit through the sling swivel I just bought. And, the new hand guard band doesn't quite match the metal on the rifle (this new band is brownish and my rile is mainly just worn bluing). I guess the sling swivel saren't interchangeable.
