Ghost Ring Sights on 870 Express Receiver/Barrel
So I just picked up the Rem 870 Express with the factory XS Ghost Ring Sights.
I'm sure most of you have seen this before, but the rear sight is on the receiver with the front dot on the barrel, of course.
Given that the barrel is removable, will I need to re-sight the shotgun any time the barrel is removed?
I'm a new firearm owner and haven't yet taken this to the range, but after purchasing the firearm, the placement of the sights now doesn't make sense to me.
