I have a RRA heavy varmint upper with bolt, bc and ch. I just got a used (new to me) m4forgery upper. It did not come with a bolt or bolt carrier. Any reason not to use the varmint bolt and bolt carrier in the new upper, or do I have to buy another? Thought I had read somewhere that they get seated such that they match one gun and its not good to switch one bolt carrier/bolt between two differnt uppers. Any truth to this or is it bull.
