I am attempting my first build of an upper. I have the bolt (fully assembled AFAIK) and the carrier (less the cam and firing pin). Duncan Long's book talks about the bolt "snapping into" the carrier and then freely moving back and forth. Mine does no such thing. I can insert it but it doesnt snap. Becaues of the friction it wont drop out but that is not the same thing. What am I doing right/wrong? Thanks.
