Cleaning question?

[davisd9]

Just added a scope to my 835.  It is a Simmons Pro-diamond 4 x 32mm.  Will the POA be affected when I take the barrel off the stock to clean it or can I just continue cleaning it as before without having to worry? I think that it will be fine but just have never had a scope of a shotgun before so I wanted to find out from others with more experience.  Thanks for any help.
