The accuracy bonus apply at least to guns and AP shells, http://ch.nicovideo.jp/biikame/blomaga/ar776809, depending on how you interpret it:

1 2 2 3 3 3 3 4 4 4 // k = 1.5 2 2 3 4 4 4 5 5 6 6 // k = 2 2 3 4 5 5 6 6 7 7 7 // k = 2.5

usually we say it's +1, +4 and +9 stars for +2, +4 and + 6 accuracy tiers.
