Assuming you are shooting with a scope accuracy doesn't change with barrel length. Windage becomes dominant at longer ranges, so mv is a big factor.
With iron sights the longer barrel sometimes (if the front and rear sight are farther apart) gives you a longer sight radius so that improves accuracy.
