Your question is a little unclear, but I believe you want to know if the scopes stay sighted in if you interchange barrels. I shoot Encores but don't change barrels very often. When I do, they are still sighted in (I still check every time that I change). The scope is attached to the barrel, so as long as the barrel moves and not the scope or mount, it should remain sighted in. I have had more experience changing barrels on my Blaser R-93, and it definitely does remain sighted in (PERFECT-but I still check every time).
