I would like to get a replacement barrel for an 870 Express, and I've been considering the Mossie made replacement barrels for a while. My question is, will the headspace have to be rechecked/re-set? The reason I ask is that if replacing the bolt I would have to have the headspace reset (I was told so by Mossberg re an older 500 20 ga,) so I imagine the converse is true, given that the chamber is integral to the barrel...am I wrong in this assumption?
