I have this Sears .22 that I am attempting to get to properly eject. It has a 'stovepipe' every 10 or so rounds, where the spent case does not clear the ejection port before the bolt in attempting to feed the next round. From what I have found, the Sears 6B was the same as the Cooey 64B, the 64B has the flat ejector and the matal mag. This rifle has the metal mag and the wire ejector. This leads me to believe that either someone put the wire ejector in once upon a time or the 6B is a model 64A, and this rifle has had the conversion for the metal mag. Does anyone have clarification on this, as well as any suggestions on the ejection issue. I have cleaned the firearm and gave the necessary parts a light coat of G96 oil. Thanks.
