Barrel removal after sighting in FF2

[gophert]

My season starts saturday and I have already sighted in the FF2.  However, I just got all my supplies to polish my barrel. 

Do you think removing the barrel on my 870 to polish would change my zeroed in FF2?  I will not be able to shoot between now ans saturday.

I say no.  I removed my barrel last year and cleaned and put back on without moving POI.  I just did the 20 gauge my son shoots without any effect.  You just have to use the Channel Locks to get 2-3 more clicks from the magazine cap.  You will be good to go.
