This about it, Hop up rubber covers up about 1~2mm of the inner barrel, it will affect your accuracy more than ANYTHING ELSE in the barrel(Such as dust, dirt, anything).
... Tightbores do increase range.
If the BB's bouncing around in a non-consistent bore the range will suffer greatly.
It's not really the tightness that matters (that's more for tuning FPS) but the consistency of the bore through-out.
