I recently purchased a rra m4 that I would like to change out the barrel on.  I would like to remove the non-chrome lined barrel and install a chrome lined one of the same profile.  I've read the tutorials on removing and installing a barrel, but I just haven't been able to get a clear answer if headspace will be affected.  I know it is a good idea to always check the headspace after removing/installing a barrel...but typically should changing a barrel change the headspace?  

Thanks!

Thanks Mike!

My next (maybe dumb) question is...Would the new barrel come "pre-headspaced" with a barrel extension?

Yes, as long as your bolt doesn't have excessive wear.

Ditto, as yours is a recent purchase you should be A-Okay.
