Is the bolt carrier group a "drop-in" assembly?

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.
 
Typically the BCG is 'standard' but some companies use a proprietary one. They are different for some calibers. Charging handle is standard but many varieties. Go to bushmaster web site to get info, call them if needed.
 
A standard AR15/M16 Bolt Carrier Group in .223/5.56 and charging handle will drop right in.

Those Bushmaster V-Match rifles (and uppers) were darn good shooters, you should be quite happy with it if it's in great shape. What's the barrel length?
