I have an opportunity to buy a match grade upper at a very reasonable price but it lacks the BCG and charging handle. Can I just buy a replacement BCG & charging handle and drop it in or does it need fitting? I've never done a "build", just swapped complete uppers and lowers and smoothed triggers. The upper I am considering is used but doesn't appear to have a lot of rounds through it. It's a Bushmaster V-match.
